i cant read my label on this wire. anyone know where it goes? its bundled up with the cable that plugs into the back of the alternator on my 87 4runner 22re. also if anyone has a good wiring diagram for an 87 please let me know. im having trouble with my truck after a rebuild and i want to go over all the wiring again. thanks

 

It's the ground wire for your alternator. It is attached to the head on one of the bolts for the powersteering bracket. It feeds up through the little space in the bracket.

I suppose it could go anywhere...as long as you create a good ground.

 

damn, thats where i had it so i guess thats not part of the problem. thanks

 

Wiring diagram is in the back of the downloadable FSM.

 

^^^ what he said

 

not to sound stupid, but what and where is the downloadable FSM?

 

downloadable fsm=factory service manual. sorry, took me a minute. where can i get that?

 

i think i found my problem. a wire from the harness that was hiding under the plenum. where does this go? what is it for? i read on another thread that there is a ground that goes to the stud on the plenum mounting area and grounds the intake manifold. is this it? it has 12 volts going to it though.

 

no really I guess I will be nice: http://www.ncttora.com/fsm/

 

beautious. thank you. any insight on that wire?

 

not sure, don't have an re and that don't look like anything on my 22r.

 

Your exactly right, it's the ground for the fuel injectors. It goes on the stud that connects the upper and lower intakes.

 

why would there be 12V to it though? Not saying it isn't though. Just curious how he's getting 12V.

 

Look just above the fuse box on the intake. If there is 12V through that wire then there is something wrong. That is a ground wire.

 

i must have done something wierd when i tested that the first time. no voltage through it. thanks for the help. im charging up the battery and hopefully she'll fire up.
