So, as some of you may have noticed in my other thread, the carb'ed 383 is going back in my 88. Well, it's bolted down now but I am starting to realize what a wiring nightmare I now have. I attempted to label everything with masking tape and a marker, but the weather has taken its toll and most of the labels are gone.

Here is where I stand on what I could/couldn't find:

Temp sensor wiring <-- Still MIA
Oil pressure wiring <-- Still MIA. I know this one is a single wire with a spade connector. Just haven't found it.

Pink power wire for distributor <-- Found it.
White tach signal wire <-- Found it.
Alternator and charging system <-- Found it.
Starter - Found it.

Overall, not bad.. There are just a bunch of other connectors, mostly apparently for things like MAF sensor, fuel injection, air conditioning etc that I don't need and would love to get rid of. They're just all bundled together and I want to make sure I have what I need before I start ripping things out.

Anyone done this recently and have any suggestions? Colors of wires I have "missing" or other tidbits would be appreciated..

 

How about a wiring schematic for the '88 TPI?
See attached.

 

That will be a huge help..

 

If the F-body is the same as a Vette then the oil pressure wire should be on a 3 pin plug with the wiring for the fuel pump switch; had common sender unit that combined both
Temp sensor should be spade terminal.

 

At the back of the engine I have #1 in the pic below. It just has a single spade terminal.

 

Well, After careful research I thought I should be able to remove all of the wires that come from the passenger side fender, into the car, and to the ECM. I removed the ECM today and got that harness mostly out.

It was my understanding that everything you need pretty much comes from the driver's side harness. I ran into a slight snag. Several of the wires I removed as part of the passenger side harness run into the one on the driver's side.

I don't recall at this second, but one (perhaps both) of the alternator plug wires was also removed as part of that harness. The red wire is still in tact but I think the brown and white wires were part of the removed wires.

I'm a bit nervous with all of the wires hanging everywhere now.

 

I guess I should have asked this question in my previous post (doh). But what are the plugs in pic 2 above? Also, where do the brown and white wires go from the alternator?
