The G-Body Swap Thread
I've been lurking this forum for awhile and got a lot of good information. I have a 1983 El Camino, originally with the 229ci and I've swapped a 2001 5.3L from a suburban into it with a 4L80E.
I'm having some issues/confusion with the wiring. I got it started a few weeks ago, but have since rethought the wiring and am still a little unsure about how this is correctly done. I'm using the fusebox that's shown on LS1Tech.
When I got it started, I had the below three red wires (PCM, Lights, Fuel Pump/Starter) all combined and sent directly to the battery. I only have these labeled that way because that's what i've identified them as powering through trial and error.
I thought that seemed a little odd, so I then tried starting it with all of those sent to KEY ON (pink wire to the ignition), except the PCM wire. I tried a few variations of that, but the only way it worked was with all going directly to Battery. With the exception of the PCM, all red wires are coming from the original El Camino wiring.
There's one additional red wire that I've marked alternator indicator. this originally went to a connector that also had a brown wire. I believe that powers the alternator indicator at the dash.
Any advice on how these wires should be ran, or what in general I should do to figure this out? Maybe i'm just over thinking it and they all go to battery?
Thanks!

I think you want full-time battery going to the fuel pump relay and starter, you need both battery and ignition (pink) to different pins on the PCM, and battery to the lights.
What's confusing me is the alternator wiring. I've got a thick wire coming of the alternator stud that goes to battery/starter/power, and a similar size wire coming from the alternator connector along with the smaller brown wire. I haven't traced the alternator connector wires, but I can see how the brown would go to alternator indicator, but what does the bigger wire do?
What did you use for a fuse box? In the past I have used the Dorman fuse blocks with relays hanging off them, but this time I am putting the fuse box under the hood, and would like something that is more waterproof. I just found Current Performance makes a couple boxes that look like they will work.

Also, mine never had A/C, so I don't think it should be HVAC.

What do you guys think this is worth? It is all original, 140K miles, very solid, zero rust, been owned by the same dude for the last 12 years. He says he only put 3K miles on it since he has had it. Lives in a nice garage. Mint interior. Drove nice. Had a surging brake pedal when braking hard. Was a little wobbly around corners and after looking at the pictures, I understand why...See if anyone spots the problem...It is kind of weird to see this car and it is 30 years old. When I bought my GTO in 1985 it was only 15 years old and it was in worse shape.
What would you pay for it?

The last pictures shows odd damage by the passenger mirror. I think a new piece of molding would hide most that of that pretty well.








This car is extremely clean and tempting me to go get it:
