Vortec v6 to vortec v8 swap.

Your missing a ground or a sensor is faulting out

Code reader won't give me a code and both grounds are hooked up?

The spark looks weak. You are aware I took the 5.7 out of a 96 and put a 4.3 ol out of a 97 in it. The white plug bhind the glovebox has two more wires both purple for the 4.3. Also has a female plug as the v8 had a male. I need a pin out of that plug

Yes I am aware. Is there a reason why you didn't swap the whole harness in?

I did swap the entire harness. Bit it seems the plug on the driver side for the 4.3 is pinned for a stick but it had a auto

That's why it's not working. The harnesses are different. It will be looking for a NSS signal and it's not getting it

Any way to fix that?

I'm not sure. Haven't ever wondered about switching from manual to auto. Usually it's the other way around

I don't think that is the issue. The bulkhead plug has 2 different wires. I really need the pinout for the bulkhead for the 4.3

One is the purple for Manuel but the v8 has a yellow and then the v8 has a black one used for a ground but the v6 has a white one for somthing?
