1972 Nova ls Swap Electrical Question Hey guys and gals,
I am in the middle of resto modding my nova. I just bought a wrecked 99 silverado. all complete with keys and yada yada.5.3l with 4l60. Well my plan is a super budget build.
I have pulled every wire off of the truck and plan to use it on my nova, from headlight to tail light. My questions are.
1. I want to delete all emission,s. Can this be done. and can someone point me in the direction to do so.
2. I am not going to even atempt at the ABS, so will i be okay to unpin them wires and delete them from the ecu?
I have more questions to follow but i want to keep it simple starting out. Thanks .

I'd like to be able to go that route, but I don't have the funds. The other reason for keeping the wiring is that I'm going to use the bcm and truck cluster. Thanks

How bad is the original wiring harness in your Nova? Personally if it's decent, I would keep it. There are several fuse boxes in the Silverado that are going to be hard to find room for and mount, not to mention how many splices you're going to end up with by using the whole harness. Running the BCM alone, intigrating it into your stock harness isn't hard, but it's more wiring. Also, you're going to need the headlight switch if you're wanting the automatic headlights to work. As for the emission stuff and ABS, you can just remove the wires and have it tuned for no emissions.

Ok i still have the truck headlight switch, so i can figure on grafting it in somehow, cause the auto lights would be cool. I understand its going to be alot of work, but being on a super tight budget with a baby on the way, i guess i have the time...lol
As far as the emisions, i can remove all that, plug the holes in the intake and such and then just remove the wires and reprgram the ecm?
I do need to keep the upstream 02's right? Thanks for all the help.

It can be done and you will have a better system than original. I did it using a 4th gen Camaro harness. It did take a while but I have VATS, the factory alarm, etc. Shoot me a PM and I will send you my wiring spreadsheet to help get you started. The ABS is possible but it takes a lot of room and you will have to get the ATS front spindles so you can run sensors in the front. It was not worth it to me.

Thanks for the reply. I dont have the existing harness for the nova. It was all hacked up when i got it. Someone tried to make the car a drag car.
Ok i still have the truck headlight switch, so i can figure on grafting it in somehow, cause the auto lights would be cool. I understand its going to be alot of work, but being on a super tight budget with a baby on the way, i guess i have the time...lol

Put a SBC/TH350 in it and enjoy it until you can afford to make the switch.
