Starting to go through my wiring!
Thank you for that! Hope my pics showed up - they don't on my screen..
So I can use the Blu wire from the stock alt to excite the new Denso alt sweet!
See the reason I'm not wanting to depin the bulkhead is cause I don't feel it's necessary the Red wire from the solenoid going into the car (amp gauge) is also the main feed for everything else (plus it's thicker than the Black wire) = eliminate the feed to the amp gauge
I understand everything now except why to loop the red/black wires from the amp gauge under the dash... makes no sense to me when you're running a completely separate charge wire
