Thanks Vader. That's a great resource!

Agreed! Thaanks!!!!

Hi, Vader I had talked to you about the electronics on my car, now if you can help me with an engine swap? I have a 1983 Trans Am original 305 Cross-Fire Fuel Injected, I want to swap it with a 350 Tuned port motor from a 87 GTA. Motor is complete, including pulleys, alt, a/c, p/s, exhaust manifolds, dist, engine harness, computer, complete injection, mas air sensor, and motor mounts. Will this work will I need to change anything else?? Fuel Pump, exhaust system, catalytic converter?

Here's a very usefull site for tpi functions and swaps has all ecm pinouts and some other usefull info.

I just had a question about those diagrams. I have a 91 Camaro RS 5.0L TBI. How will these diagrams compare to my car since they are for a firebird? I've been told that they are basically the same car. It would make sense though that the differences between them would be small/electrical.

Please help, I'm getting ready to pull my dash to swap it with a 4th Gen.

Thanks Vader!

Sincerely,
Kurt

Vader,Thanks for the reply. My engine is a carbureted 355,and the high stall converter is locked up manually by a modification to the valve body involving a plastic check ball in a passage under the lockup switch.Works well,lockup is very firm,but not excessive.High Tech Transmission in Houma,did extensive modifications to my trans,and it has taken a good trouncing over the past two years,and still works just like it did when installed.
Thanks again,
"The Accelerator"

where can i find one of these for a 96 firebird? lt1

thought i would add this here as its mostly wiring related.

i did a quick read through on it & it seems pretty complete.
how to convert from manual to power windows on your thirdgen,.

http://www.p71interceptor.com/thirdgen/powerwindows/

Hello. Do any of you know where I can get the pin outs for the engine to under dash wiring harness. I already have the pin outs for the ecm and have all that worked out but It is the harness that would connect the computer and the engine wiring harness to the underdash wiring harness. Please help me out if you have any information. I am stumped right now.

i have a 1987 iroc z its a factory automatic car but i cannot find the torque converter lock sensor plug im not sure if its been cut off or it needs an extension plug can anyone help me with a wiring diagram for my car??

Did the diagram in the first post in that thread not help at all?

Wow i know i revived a old thread but the author of chevythunder deserves a
Award.

That was by far the most helpful link PERIOD on any forum.

AWESOME!! thanks a ton! wish i had seen this earlier, but it will still answer tons of questions. huge thanks!

Holy crap, I work at Autozone and I didn't even realize these resourses were available! Thanks!

thank you - thank you - thank you!

Ok, I looked through a couple of the diagrams from up top. It looks to me that if I can find a 90 or 91 3.1L V6 engine harness, I can use it for my basis for a TPI retro fit. I would only have to add a couple injector plugs and do away with the temperature switch for the tranny? This maybe easier than trying to repin a tbi harness? Yes, no any thoughts, thanks.

try these guys at Automotive Hobbyists (info@ahdol.com) - i paid 11.99 and i got an entire colorcoded set of diagrams for the entire car, which is a 90 camaro. does not matter what model they give you everything for that year.
EVERYTHING!
best 12.00 i ever spent on the car. and it is e-mailed to you so that you download it and only print the pages you need.

is the link working for the diagrams anymore? it shows as busted to me.

Unfortunately, they now require you to register. Get to a point and select "Repair Guides", and they'll have you register. Then you can see all diagrams for all 82-92 of the model you've selected as your car.

^^^ That link no longer works btw...

Yeah, I can't imagine why? The link was valid in 2005.

Anyone keep the info? We have some seriously foobarred wiring in our LeMon's Camaro due to too many kills switches, car alarms, remote start, and the like...

I can only imagine what that **** must look like. lol...its giving me anxiety just thinking about it.

i have a question for you this is my first time on this website i have a problem with my car it starts and when i turn it of and try to turn it back on it hezatates to start then i wait a lil bit then it turns on would you happen to know wat the problem is i got a new battery and alternator would you happen to know

Link doesnt work.....for me at least.

me neither

that link hasnt been good for a while, Autozone's website has really stripped useful info for our cars, my uncle is a manager for pep boys service side and got me a whole lot of diagrams(dont know if its complete) but i will scan them and post a new thread, maybe it will come a new sticky

For anybody needing thirdgen wiring schematics, i have a full set on my computer ready to send to anybody who wants them,

it is the 89 model year wiring for 2.8(dont know if its the same for 3.1),5.0 E,5.0F, and 5.7

also includes body wiring and ac/wiper washer assembly, i have 9 pages total but if you only want your motor it would be 6

if the mods would rather me post it in a thread i will be happy to do that as well

got them thanks to my dad and uncle back when i was 17 and just dug them up today

I am trying to wire my wipers to a togal switch can anyone help?

ok, so heres the story... I started an engine fire and fried the computer wiring harness to the girlfriends 1986 Carberated 305 HO along with burning lots of other components...long story short we went back to vacuum controled while upgrading the cam, timing chain and cover, valve job, intake manifold, holly carb, valve covers, headers and new vacuum distributor...now we have an issue with the speedometer not working (since it was computer controlled) so...is there a way to bypass the computer and hook it up directly or is there another option besides going back old school with a cable on the speedometer?

Be sure that you have electrical speedo first, if you do then pull the dashboard back and be sure that the VSS buffer box wasn't damaged second. If the box still looks good visually then check your wiring behind the engine going to the drivers side. The wires for the speedo should be running that direction through the C100 at the firewall. With you having a fire my first guess would be that you burned up the wires coming from the transmission going to the VSS. You'll probably just have to splice a wire or two and have it back running again.

so the fire never got through the firewall behind the engine but burnt up the cable going to the transmission (the speed sensor cable that runs to the computer which we pulled out). The speed cable going to the cruise control is intact and the wires going to the c100 were all ok...so in order to get it running I have to splice some wires? to where? I think I have to get a new sensor clip also since it burned up...

trace your wires from the speed sensor to the c100 and be sure that there aren't any damaged wires, if there are replace or repair them.

The link won't work for me ...
Thanks

Yes, it hasn't worked for quite a while now.

VACUUM GAUGE INSTALLATION
hello, i need some help installing a vacuum gauge in my 83 z28.

My problem is, i cant find the 12v dash lights, and the 12v ignition switch under the dash, is it a fuse or what?

http://www.princessauto.com/componen...438_manual.pdf

I put my 89 305 and harness into a 91 that had a v6 in it. Now I am having wiring trouble. My tbi injectors are giving me trouble. And my electric door locks not working, and acc fuse keeps popping.

are the harnesses not plug and play changable?

Through work, I can look up any wiring diagram in mitchell. If someone could narrow down how interchangeable the wiring is for third gens, I can try to put them here for all to see. Its just a lot of diagrams to copy and paste.

Thanks for responding. How can I get that info? Is it a site I can get on to?

Its through mitchell, but how I need to look it up by exactly what it is. If you need one, just pm me with what you have and I will get them for you.

I need the diagram for the plugs that are going to the ecm from inside the dash for a 91 rs v6 and also an 89 rs v8 305 tbi.

If I had the diagrams for bothe cars I could probably figure it out.

They seem to differ and I'm stuck.

Thanks for your help.

could you please send me the diagrams as well bro. I have a back halved 91 bbc blown ,nitroused t.a. on the street and am just looking for the gas gauge wire so i can hook up my fuel cell sending unit.. i was hoping for 80 mpg but i missed my mark..... grin. trying to find wire color,,, maybe purple?

I have an 89 camaro 2.8. It appears as if a wire is missing from the rear of the alternator. There is just a connector with no wire. Do you know what this wire would do? The guage just shows an 8 not the 13 it used to. I am at a loss because I can't find a disconnected wire. Please help??

Thank you ocgael
