Im in the middle of doing my wiring for my DOHc swap but the first thing I tried is not working out to well. I went to DOHCfiero.com but the pinout for the C203 connector they have is different than mine. I dont know what year the harness is from but its a 4cyl. harness. The car it is going into use to be a v6.
The pinout I have is...
A---empty
B---orange/black
C---brown/white
D---empty
E---brown
F---pink/black
G---yellow
H---grey
J---empty
K---empty
L---brown/white
M---black/white
N---empty
P---tan/black
R---pink/white

Can someone tell what I hook to what?

I made this up for a forum member the other day, it is for a 88 2.8L

White connector- engine side of harness Black connectors- car side of harness.

C203 1988 2.8L Fiero

Wire colors will be listed from the white connector first, with the second color being in the black connector ( if applicable)

TERMINAL COLOR(S) CIRCUIT

A Not found
B Orange – Orange/Black Fuel pump relay +12v feed
C Brown/White Service engine soon light circuit
D Light Blue AC Pressure cycling switch
E Tan Oil pressure signal
F Pink/Black ECM +12v
G Yellow Vehicle speed sensor (VSS)
H Brown ECM VSS Input ( from speedo)

J Pink/White-Pink Injector bank 1 fuse
K Pink-Pink/White Injector bank 2 fuse
L Tan/White Fuel pump circuit
M Black/White Instrument cluster ground
N Black/White AC compressor control relay
P Purple Torque convertor clutch override
R Purple/White Vehicle speed sensor

A positive for you jelly,thanks alot. I dont have the 2 pink wirees for the injectors. Do you know if I need these for the 3.4 DOHC swap.

Depends on the wiring of the ECM. Does the ECM supply power to each injector with a common ground? Does the ECM supply power and ground? If so, then you won't need them. If the ECM supplies ground and the injectors get power from the fuse box, then you will need them. It seems that most SFI systems are the former (don't need them) and MFI are the latter (do need them).

What about the shift light wire?

I have a 88 2.5l harness. I have checked www.DOHCfiero.com but the colors arent matching up.Can some one help me out with what goes where?

Are there any plugs that I can remove from the harness? Tranny plug, ac plug?
