Part numbers of common electrical connectors with LS engine swaps
LTX and LSXPutting LT1s, LS1s, and their variants into Third Gens is becoming more popular. This board is for those who are doing and have done the swaps so they can discuss all of their technical aspects including repairs, swap info, and performance upgrades.

That's a good question.
So that prompted another internet search for an 84-9449 crimp tool and interestingly, it yielded another Grote crimper and the catalogue blurb is entirely different from the one I saw the other day which prompted me to post.
No mention of Packard terminals. It's now Deutsch and Weather Pack. So now, with this new information my question is whether the description posted below is of any use in a wiring harness rework.
I'll be looking to modernize and weatherproof my existing wiring harness. Along with replacing relays that have a flat tab terminal to which I fasten a crimped female disconnect (Yes, I'm aware there's a 4-socket connector available but I choose not to use as it), I'd like a Weather Pack style connector. I'd prefer to terminate my own ends rather than getting a relay with a pigtail as that pigtail generally entails a butt-splice.
So I'd go from this:
But I'd forgo the pigtail and build my own connector assembly.
Will that Grote tool at least handle the task of that style connector?
Then there's the power distribution block discussed in another thread. At this time I've no idea what kind of terminals are needed. I'll deal with that when the time comes.
Re: Part numbers of common electrical connectors with LS engine swaps
There are still a few Metri-Pack 150 terminal part numbers I have never been able to find. If somebody knows please give me a shout. Thanks!
1. I'd like to find the silver versions of these to use with O2 sensor. I do know of the Gold part numbers. Maybe there is only Tin and Gold available for these Male terminals?
Silver version of 12077628, M/P 150 male terminal sealed (0.5 - 0.35 mm2).
Silver version of 12045773, M/P 150 male terminal sealed (0.8 - 0.5 mm2).
2. Tin plated version of 12160223, M/P 150 female terminal sealed (1.0 - 0.8 mm2). The Silver part number I already have is fine but hoping maybe the tin is a little cheaper?
Re: Part numbers of common electrical connectors with LS engine swaps
Oh, I see. I'll probably stick with the silver plated 12160223 then.
I'm learning to avoid using 15326225. It has a larger 16-20 AWG wire range that my tools don't like. The Delphi tool under crimps 18 AWG wire so what I end up doing is make a full crimp on position C, and follow up with "2 clicks after seating" on position E. Not 1 click, not 3 clicks... but 2 clicks. I got tired of antics like this and bought the Rennsteig tool.
But it turns out that even though 15326225 terminal is listed as compatible with my Rennteig 1527 tool, the terminal is actually oversized and doesn't sit in the dies properly. The tool will make a good crimp first try, but there are antics again bending wings and such to get it prepped for the crimp. Things play out better when I use 12160223 for 16-18 AWG wire, and 12160222 or 12084200 for 20 AWG wire.
Thanks for your time looking into this for me. I appreciate it.
Re: Part numbers of common electrical connectors with LS engine swaps
This thread is not done yet and the 1-pagers will be getting updates. I've made my first practice harness (which was just a partial harness for learning purposes) and found a couple errors in the 1-pagers. I am also learning which terminals are "preferred parts" for the task.

Re: Part numbers of common electrical connectors with LS engine swaps
There's as much good information here on the types of connectors as there is on the commonality of the LS swap hardware.
Seems a good place to ask about Deutsche connectors. Are they available as both an open barrel or a closed barrel? Comments on another forum seem to confirm this. And if that's the case, I can see the less finicky closed barrel used for my rewiring project.
Re: Part numbers of common electrical connectors with LS engine swaps
Yes, there are stamped and formed contacts (open barrel), and solid contacts (closed barrel).
Whenever you're talking about a product owned by TE Connectivity (such as Deutsch), there is always outstanding documentation located at their website, https://www.te.com/
Everything, and I mean EVERTHING, has a technical datasheet somewhere on their website that will tell you what are the options and compatible parts. Example of DTM connector datasheet, https://www.te.com/usa-en/product-CA....datasheet.pdf
You really gotta pay close attention to the seal dimensions with the Deutsch stuff. Much of it is made for off-highway industry with thick wire insulation (GXL wire). You often have to select a special part number for thin wire seal to work with TXL wire.
Re: Part numbers of common electrical connectors with LS engine swaps
Not sure how I missed this thread, but I'll contribute a few 3rd gen connectors that were missed. I'm not sure what the C208 was for, but I never used it on any of my swap harnesses
C100 - well documented. I bought up the last few or so I could find when I switched from used to new wiring. Those ran out, so I had to order 500 to get mouser to re-open production. Needless to say, I've got a few spares
C207 - Conn 12045784. This was D/C most places so I googled PNs until one landed with QTY. It was a company that buys up obsolete connectors and sells them to nerds like me
18ga term 12162595
12ga term I'll have to update when I find this. Wasn't in my master excel for some reason
C221 - Conn 12015344 85-89 cars have this near the C207. It houses INJ1/2 fuses and fan wiring
18ga term 12162595
HVAC - Conn 12052623 Large black connector on the HVAC box that connects to the engine harness
18ga term 12020125

HVAC 12v - Conn 12015987 85-89 cars had an external connector for the 12v battery cable feeding the HVAC box

Wiper late model - these were attached to the engine harness for some years. LG goes on top, SM on the bottom directly into the motor. Some years had an inline 3pin weatherpack near the bottom, but I went strait to the motor and skipped that short harness section

Early model wiper. 82-84's had 1 and 2 spd wipers different from the late models

Re: Part numbers of common electrical connectors with LS engine swaps
Here are the most used tools in my arsenal
TL Harbor freight strippers. I haven't noticed much difference from the Klein's they copied $6 vs $50
White performance T-11E Most 10-12ga terminals are crimped with these
White performance T-18E Almost everything crimps with this. MP150, GT150, Weatherpack, 100W, Relay terminals etc
TR Klein cast iron crimpers. I use these for rings and basic un-insulated terminals
White performance T-15 AAW 56-/59 series double crimps. Very limited use
Sargent 3303 Meant for micro .64mm terminals. I use it for E40, E38 and E67 ECU terminals and those dumb Holley CAN connector terminals
Bottom row
Delphi 150 depin tool. Do not pry anything with this, but it will release almost any terminal with some finesse
Basic engineers pocket screwdriver. Pop caps, TPAs, wings etc. A couple large terminals can have their tabs released with this
Amazon special weatherpack tool. Use for weather packs, nothing else
Using the T-15 double crimper. Most commonly used on series 56/59 terminals in AAW chassis harness kits, but I've seen a couple ring terminals using the same basic crimp method. 59 series are still used for all 3rd gen headlight bulbs. Engine harness uses are extremely limited
Most crimpers have a basic non-sprung version with shorter handles. Typically, they have an X shaped hinge
I've found the dies aren't cut properly on most, so terminals never fully crimp for the most common wire/terminal sizes. Had too many connectors pull off the wires
I also dislike ratcheting strippers/crimpers. Total personal preference
Re: Part numbers of common electrical connectors with LS engine swaps
Making professional crimps with common terminals
Start with crimpers for non-insulated terminals. Need the tooth in one slot and simple butt crimps in another. Cast iron versions are wider which help
Slip some shrink tubing over the cable
Ideally, use non-insulated terminals. If none are available, then use pliers to pop the plastic jacket off before starting
Use the crimper tool on the terminal barrel on the split. Typical ugly weak crimp
Reload the barrel into the butt crimp section but sideways. Crimp and protect with shrink tubing
The wire absolutely isn't coming out of that crimp and will pass any UL weight test
Re: Part numbers of common electrical connectors with LS engine swaps
Relays
I prefer to buy relay sockets in bulk from Amazon/Ebay. Singles vs linking sockets. The linking version clips onto the basic dorman 85668 fuseblocks. Cheaper sockets usually come pre-terminated with whatever wire. I depin the supplied wire which is often junk aluminum/CCA or some wierd pinout like the singles with a diode built in
Terminals Basic 1/4" F spade with a retention tang. This is semi-ubiquitous, so these PNs aren't the only options
18ga TE-60838-1
12ga TE-160913-4
Re: Part numbers of common electrical connectors with LS engine swaps
Somewhat on topic, although not necessarily LS swap related, is a question regarding the C100 bulkhead connector.
I'm looking to rework my engine bay harness by consolidating the assortment of relays and fuse holders into one location near the battery.
Doing that with a power distribution center (relays and fuses in one box) will allow me to thin out some of the harness while also eliminating the fusible links (never much cared for them).
This means replacing those linked wires (3 x #10) that go to the C100. The question is what terminals and tooling are used on the 80's era harness? Are they even still available?
I'm equipped (more or less) for weather/metri pack and Deutch style terminals but I'm pretty sure the C100 isn't that.
Thanks in advance.
The C100 connector use three different types of Packard/ Delphi unsealed Metri-Pack terminals. Metri-pack 630 series, Metri-pack 480 series and Metri-pack 280 series.
Re: Part numbers of common electrical connectors with LS engine swaps
That is really valuable information that vorteciroc posted about the C100 connector. skinny, thank you for posting the link to his thread as well as posting the short answer here in this thread!

Third gen is a fantastic resource with a lot of solid contributors.
Although I'll not get as deep as some here (I've done most of the heavy lifting already) simple questions such as a terminal type seem accurate and easy to find.
Re: Part numbers of common electrical connectors with LS engine swaps
True enough although it wasn't forthcoming in an internet search. Vorteciroc's original post did show up however.
Seems too that his reply is far more detailed i.e. P/N's aplenty, than his post from 2010. It also appears that a lot of his content hasn't stood up to a decade and half of being posted. Pictures and such, as referenced in his text are nowhere to be seen.
That said, I have to say thanks for keeping the historical record alive. This stuff is priceless.
Is this a sticky?

If I remember right, vorteciroc told me the male side is Metri-Pack 280, and the female side is Pac-Con. That's why I didn't list any female MP 280 part numbers.
Will MP 280 female terminals fit and retain in the connector?

I don't know, it's been a long time since I used electrical tape. I use shrink tube to insulate. And have a roll of Tesa 51036 for when I need to wrap something. I'm not sure how the Tesa weathers over time. Nice thing though is it doesn't have the sticky gooey mess of electrical tape.
Re: Part numbers of common electrical connectors with LS engine swaps
The Color Diagram in the Hyper-link that you posted is absolutely incorrect.
The Connector Body is labeled incorrectly as to where the Terminal Positions are designated (A, B, C)...
The Image that you posted is however correct in that regard.
This style Oil pressure Transducer (Sensor) is Terminated differently in different Model Year Vehicles...
There is no single consistent Terminal placement/ Pin-Out.
Here is another example:

Re: Part numbers of common electrical connectors with LS engine swaps
Do you happen to have a Helm/GM service manual for a c6 corvette that has the ls3? I believe that will have the correct pinout. If not no worries, I’ll just keep repining it until I find a configuration that works

What my Father said, was that C207 Connection is all Metri-Pack 280 Series...
But that the Driver Side Dash Harness to Rear Body Harness Connection is most often Mixed (C208 in some Model Years, C206 in other Model Years, and even some other Connector variants in earlier production Vehicles).
The Male Terminals are still Metri-Pack 280, but the Female Terminals are often Pack-Con I Series.

Which Model Year Corvette?
I'll go see if I still have that information in my Father's GM Engineering Database Server.

The sensor I have is GM 12673134 which I thought was the same as a GM 12677836 (2008 corvette with the 6.2L LS3 or 7.0 LS7) but perhaps the pinout of a 2013 Camaro 6.2L (supercharged LSA in the ZL1 or Naturally aspirated L99 in the SS both call for the same GM 12673134 sensor) in a Helm/GM service manual would be more accurate for the GM 12673134 sensor.
Re: Part numbers of common electrical connectors with LS engine swaps
2010 Camaro with the 6.2L LS3 shows GM sensor 12673134.
2010 Service manual shows the same exact pinout for the 6.2L LS3 as the LS4 image shown above, so I'll give that a try. They only list part numbers for the connector, not the sensor itself in the service manual which is where this image was taken:

The pinout I posted which was the same as the LS4 worked! Transducer matched mechanical gauge for oil pressure. All good! Thanks!
