BHA2102 and Alpine CDE-143BT
Hello, I purchased the BHA2102 wiring harness and the Alpine CDE-143BT head unit. I am trying to wire them together but so far with no luck. The area where I think I am having the problem is on the BHA2102 there seem to be two yellow "12V battery constants". Do I need to wire them both? Or is one to the battery lead on the unit harness enough? Also, I have no clue where to connect the "illumination" lead from the unit harness.
Any information would be helpful.
