These are the wire descriptions i foun in the sticky and my connector. i need to kno what to hook some of them up to, some of them are different from mine though.(above)

Now for what i did(below)
-------------------------------------------------------------------

C1 is the starter wire for cranking, hooked it up
C2 is fuel pump, ran it to fuel pump wire, it primes and everything
G1/ G4 i hooked both of them to my IGN wire from my car, they get power when my key is on

****** i am assuming my problem lies in B1 and/or H6*******


any advice is appreciated, thank you.

 

anyone have any ideas?

 

ok guys, i got the proper pinout descriptions to match my harness, so now i have some different questions, more specific. my information says the drk blu from B1 goes from ccm to pcm-what is the ccm and how do i do this? i tried some things with the wires to try and get a feel of what to do with and one of my conclusions is that (do) i need to get a passkey module (anti theft module) for the harness and hook it in order for the drk blu fuel signal to function properly? also my description says i have a variable oriface feed and return wire, what are these? also i have a neutral safety ground and a switched ground for neutral/park, are these supposed to be grounded in "run" or not grounded in "Run". one has ground and one doesnt and i dont know where they are supposed to go to. soon as i remember to brng the paper with the pin descripts i will post them for you to c. i appreciate any help i can get.

 

What year of harness are you working with?

 

its a 94 caprice 9c1 motor
