HU problem

[Dtrickz 10+ year member]

i had a panasonic hu in my g/f's blazer..well we got a trailblazer and i put it in there, had everything hooked up right...the problem was the hu would only be on when the lights were on...no matter if it was the headlights or parking lights..one of them had to be on for it to work...i've installed many hu and this was the first one i ever had problems with...i guess it has something to do with the automatic lights..i've already sold the cd player and put the stock back in..it was just bothering me cause i messed with it for hours and couldnt get it to work

You need to switch the illumination wire with the acc wire. You mixed them up.
