3rd Gen Wiring prep
3rd Gen Wiring prep
I know this has been covered multiple times in many places but I just cant seem to find the info I need. 1988 IROC main engine harness is out, going to be 383 stoker, carbed with mechanical fuel pump, I have not touched the dash wiring or lighting harness. Is there a schematic somewhere that doesnt make me reinvent the wheel for prepping my my existing 3rd gen engine harness?

Re: 3rd Gen Wiring prep
If you can't follow the guide, I suggest you let someone else handle what you need done. I am not trying to be an ***, but this is really easy stuff, especially if you're going carbureted, there is even less to do than an EFI swap. There are only about 7-9 wires you need from the original engine side harness.

Re: 3rd Gen Wiring prep
I can answer, I build swap harnesses. You're asking for hand holding at this point. All the info is here on the site already, it is in the how to prep a 3rd gen harness thread.
You haven't given any details on what your car is, or if you're running fans, trans, speedo, etc. you might want to let someone else handle it.

Re: 3rd Gen Wiring prep
Well maybe if you would have said that I would have bought one from you. Yes I am looking for hand holding but now I would rather scrap the car in a field than buy one from you or get advice from you. Your a putz again either help and answer the question or take your passive- agressive attitude and shove it.
I wasn't being condescending before but since you insist on calling names... I wasn't trying to sell you a harness, it is likely that you wouldn't be able to afford my services anyway. And it's **YOU'RE** a putz, not your a putz.

I am not being passive aggressive, I am just giving out a hard pill to swallow. Lot's of people take on projects that are way over their head, as it seems to be with this for you. The info you need is in that prep thread, Pocket laid out all that is needed to isolate the factory harness to make it "stand alone". 2 for power, starter, coil power, tach, alternator field, oil pressure and temp and there is a ground on some years
