Can anyone with an LT1 tell me where the pcm ground is.....doing a V6>v8 swap and I only have one wht/black 18AWG wire goint to a ground right above the battery into the block..Is there another one??? if so what color is the wire and where can I ground it to??

 

I guess you mean above the starter (not battery). Besides the grounds to the coil stud, there are no other grounds on the engine harness that hook up with a wire lug.

 

See my problem is that I have 4 injectors not getting power to them to fire (1 7 4 6) I really have no clue on how to fix

 

You are not providing enough info on the swap. Give the year of the car and what you are swapping into it. Sounds like you have a blown injector fuse or don't have the proper wiring to provide power to those injectors. 1 7 4 6 are all on one fuse (circuit).

 

The car is a 95 V6 Auto swapped to an LT1 T56 of the same year or so I was told. already checked both fuses and I have swapped PCM's so the problem is not in the computer. If you know anyone that need a 95 PCM for LT1 M^ let me know

 

If you have power at the fuse and not at the injectors, you need to check in between. schematic Check for voltage at "B" on the 8 cavity flat connector (C105 pic for reference) on the RH shock tower.

 

We figured out that that pin doesnt have power... this is because my 95 V6 doesnt have any plug at all for the C105 connector to plug into. Do I need to get a body harness form a 95 Camaro and does it have to be V8? Or should I just run power to the pins that need it

O2s get power from F on C100, Inj from B C105 etc

 

That's a common problem with conversions. When you said the injector fuses were ok, I assumed you had the fuse block and wiring from the LT1 car. All you need to do is find a way to provide switched power for that injector feed and you should be good to go.

 

Should I just replace the harness in the front. If so do you know where I can get one. If i need to do this is there anything else I would need to replace. And if I do need to replace it do you know where I can find instructions on how to get the job done quickly

 

It's up to you what you want to do. Salvage yard and factory service manual. Those things will be of the most value.

 

Well I'm working on a lmited budget, I was just wondering if you knew much about it and how much would i need to take out to get to it, plus if it links with anything around the drivers side
