Default Where does this wire go...

Like above, anyone have any ideas where this wire plugs in to? It's made with 3 wires 2 red and 1 black, one of the red ones goes into the fuse/relay box. Also my fans don't turn on at all, not when the temp is high or when the AC is on, hope this wire has something to do with that?

Looks like the AIR pump sensor.

I may be wrong though.

I don't think it has anything to do with your fans, my sisters 1997 firebird has that same wire unhooked and I didn't find where to plug it.

Where does it come from.. The MAF has that same end, but you probably have that plugged in already. My Fans went out also the other day, I hard wired them as constant run.

check your fan relays usually the problem if happens suddenly. put your hand on it and feel if it clicks while someone else turns the car and the ac on.

i had a fuel pump relay go out on me before in my mustang and it went out an unusal way. I shut the car off and while walking around it i heard that the pump was still running!!! with keys in my hand!!!

was a bad day for me. ripped my whole mustang apart looking foir the damn relay.
6 hours later and still no luck i got pissed and punched my driver seat as hard as i could annd the ****** finally shut off. the damn relay was mounted directly uner the drivers seat sticking up thru the carpet.

little off topic but i thought it may make one of yous laugh.

In the back of your manifold- on that driver side- see if there is a little box/ solenoid hanging w/ 2 elbows on it. If not- im pretty sure it is the AIR pump connector. - i'd say its nothing to worry about..

thats what i thought also
check your temp sensor on your water pump if you unplug it with the engine running your fans should turn on if they do that sensor is bad

My car has always had that unplugged as well and I just never really looked around for it. Now I may have too though.
