need the wires (the colors) that need power for the TBI and Spark to work. I am pulling my hair out on this thing. If you have any insight please call me at 1-910-818-3929. The city Say the truck needs to run by Mon. morning or it is a $250 Fine and it gets impounded.

TBI setup is from a 1990 K5 Blazer

I am not getting fuel through the injectors. I am getting fuel to the throttle body.

Are the steering column wires needed?

What wires need what power? What color wires need switched power? I am lost with this thing. Been working on it for 7-10 days now. Need it ready for URE this weekend.
