Anyone familiar with how to wire the 4.0 alternator?
I've tried logging into their forum but my membership still hasn't been activated.
There is one blue wire and one brown wire coming from the PCM that do not have labels and I can't figure out where else they'd go. Do they go to the field terminals on the alternator? If so, which is which?
Also, is there a ground anywhere?
Y'all have helped a ton the past few days, I really appreciate it.
The Hesco harness was made to use with there MPI. I just pulled out my alt to day but haven't gotten to the point to figure out the wiring, but will take a look tomorrow.

That wire needs to be grounded for the starter relay to work. The neutral safety switch provides that ground when the transmission is in "Park" or "Neutral". I suspect the switch is near the base of the steering column under the dash, but I'm not familiar with auto CJ's.
