Thread: need help with where this connector goes

I was replacing plugs and wires on my 95 GP with the 3100 and for the life of me I disconnected this connector from somewhere and cannot find where to plug it back into. Its been 2 days since I unplugged it and now can't find where to plug it into...lol

It comes out of the main harness right behind the alternator and this big harness goes into the firewall bottom passenger side. There are a couple of other connectors also, one goes to the alternator and the other goes to the coil packs passenger side.

Just a guess here, but from what I normally see the EVAP connector is usually red.

Agreed and my first thought, evap is red.

I could make a bunch of guesses. Reality is.. GM color coded things and that's an evap color.

Do you have a ps pressure sensor on the bottom of the pump or something like that? Here's how I'd try to find it. Move that wire around in a circle as far as it'll go. Then subtract 2-4 inches of distance because every wire has slack, except your alt connection (it's a 3100 thing). From there.. search for anything that is missing it's connector. Also hook up an OBD reader and see if any codes/sensors aren't reporting or have reported an issue.
