Stereo wire to acc switch. Help.
Just to update. Last weekend I found what turned out to be just a loose connection on the new fusion wiring harness that carried the power and amp remote turn on (among others) where it plugs into the back of the HU. Seems funny that it would get one connection but not the others. But, I had
1) everything working
2) amp turn on not working
3) nothing working - no power
4) back to all good.
It must be real finicky. My ZLD is mounted right below HU so getting my hands to the back of the HU is tough.
Running yellow power wire all the way back to bus bar was the trick for the ACC switch to function as intended.
