I'm trying to figure out the location of a broken or shorted out wire related to the fuel injectors. I'm having difficulty identifying the wires because they have faded and changed color in the engine compartment, due to age. Can anyone supply a wiring diagram for the EGR.

I feel your pain, maybe below will help.

Pink wire connects to three odd injectors
Blue/Black wire connects to three odd injectors
Pink/white wire connects to three even injectors
Green/Black wire connects to three even injectors

Also on C520 (the 6 pin connector between the injection harness and the engine harness is

Tan - Cold start injector
Purple/White - Cold start injector



Here is the diagram I have for the EGR system



Hope this helps!

Thanks Ponnari. That is exactly what I needed, even though I asked the wrong question. I meant for the topic to say; "ECM Wiring Diagram..." I got my acronyms mixed up. I could't figure out why no one was responding to my post. Duh.

Your welcome shurlbert, glad to help! I know what you mean, all those Fiero acronyms flying around in our heads, lol.
