I have a 1999 silverado 4.3 blown up and swapping 1999 4.8 into it. My PNP has the 2 connectors 7 pin and 4 pin. The harness I got out of a 1999 silverado automatic has 10 NOT 11 wires going to PNP, purple/white on pin E is not in the harness> Also I found both greens in the fuse block connector but unsure which of the greens goes to which fuse block pin A9 or E3.

Need to know if I can ignore the purple or have to run it somewhere, and how to figure out which green pins out to which connector position.

A pinout for the fuse block connector and the ECM pins the 4 pin connector goes to would be nice.

Thanks very much in advance.

Is this supposed to be all Camaro - Firebird. If so sorry didn't realize, still any help would be appreciated.

 

purple is starter relay voltage supply.
Only gives power to starter relay in P or N

as for the green...trace with a multimeter and check which is which. Or, hook em up one way and if the reverse lights come on in park but not reverse...you'll know you have them backwards

So I can forget about the Purple? Leave it hang?

 

Oops wasn't thinking, your saying Park, so this purple needs run correct, does it go to the fuse box connect, I think that is C1
