Hi, what are these 2 plugs going into the ECM? is one of them the c-207? and if possible is there a pin-out dialgram for the plugs, my car is a 84z 305HO(vinG), i am trying to locate the vss buffer wire on that, so i can tap my scv wire from my 4th delco radio into it, thanks.

 

hey i think i got it narrow down to the brown wire on C207 pin K is the vss buffer and something about pin 16 and C1, can anybody out there have some more info about which might be the C207 and what my other harness is in the above pic? thanks.

 

i already did a seach and can't seem to find the info for my year, anybody out there that can help with the pin-out diagram? anybody?

 

I just check the ECM and under pin K there's no brown wire, but there are another brown wire, can anybody let me know what that wire is? any wiring diagram would help?
