We want your Wiring Diagrams! :kiss: Diagrams needed are for Yj wranglers only and should be posted under the Yj Technical Information forum. *Hint hint, rusty, cough, tomb raider* Needed: 87'-90' engine electrical wiring diagram 87'-90' dash wiring diagram 91'-95' engine electrical wiring diagram 91'-95' dash wiring diagram 87'-95' chassis.. Here is the diagram for the alternator. 1995 YJ. That's it.from Jeep. 5.3L Chevy LM7, 4L60e, NV233C Transfer Case with electronic Shift, 2.5" OME 2.5" Lift.. Yes, that's the wiring diagram from the 95 4.0. and no your '89 does not have an ASD. Hard to tell where those wires run from in your pics. If it the green and orange wires go to that.
As for wire 2 I think it connect to the screw on the back of the alternator where wire 1 is. Last is wire 3. I figure one of the has to attach to the volt meter. Any help or advice will do. I found on another thread that had the wire diagram for the 88/89 bulkhead connector.. start there. It also is a nice junction between the PCM, alternator, and batteries, plus it gives a nice place to run accessories both with the keys on and off; and as you are eliminating unused wiring you now have fusable line.. here's a link to all YJ wiring diagrams---after you scroll thru the various years, there's more diagrams that may.
