I hav six sets of wires in my engine bay that aren't hooked up! If you know what they go to and how important they are it would be very helpful! About the car its a 88 firebird with a tuned port 350. Automatic trans and the whole intake has been swapped out for a edelbrock tpi or mpfi whatever. It's using the factory harness and all the smog stuff is pretty much missing!

1sr one is a 5 pin connector near the battery tray and it has the following wires in it. If it matters the battery has been relocated to the trunk!

Female connector
green wire
blue w/black stripe
black
tan
blue w/ white stripe

Next one is coming from around the distributor base somewhere its a 2 pin and the colors are

pink w/ a black stripe
light grey

I also have a single green wire with a male connector coming out of the fuel injector harness driver side behing the injectors

also coming from the rear of the motor there is a 2 pin plug that has a orange connector the wire colors are

orange
brown w/ a white stripe

I know it's amazing it runs at all lol!!! alright next one which is probably the most important one actually has a sensor on it but it's just hanging. My guess on the sensor is a air intake temp but I have no idea really!!! I t is located by the air intake. Where should this sensor be it has.

orange
black w/ white stripe

Alright last one is a male connector on the passenger side coming from the harness on the lower part of the shock tower and it is also a 2 pin connector colors are

grey
black

like I said any help would highly be appreciated. The guy i got the car from was a hack lol. I cant upload pictures right now but I will try to tomorrow. thanks again

 

I dont know if this will be much help but I would look in a haynes maual and look at the wiring diagram. That way you know for sure what goes to what.

 

Cruise Control servo.

EGR solenoid, note that the PNK/BLK is +12 IGN power.

EGR vacuum sensor diagnostic connector.

Maybe tan/wht? That would be for the back up fuel pump switch that is controlled via oil pressure.

Not sure, MAT should be a tan and a black wire. A picture would be helpful.

Not sure on this one. What would be in that area?

That last one, gray and black wires, that may be for the A/C high pressure switch to turn on the aux cooling fan.

alright sweet thanks for the help. I think the only one that is important is that sensor i'm pretty sure it's a intake air temp sensor. I'm thinking the one that noboody knows is for the smog stuff that comes off the header if anyone was wondering. Thanks for the help I couldn't read the wiring diagrams on my computer everything was to small to read. Thanks again
