i wired in my head unit into my 03 f150. and when i did i guess the acessorie wire touched a ground or somethin so now that wire is not getting power. when i touch it to the constant it works though. how do i wire this to something else to get power besides doing a switch?

check your car fuses.

i did. all the ones in the fuse box are good. and the illumination on the ac knobs doesnt work if that helps

if it's not getting power, it's definitely most likely either a fuse or a fuseable link. I would def. try replacing the radio fuses and such regardless if they look alright just to make sure.

But if you can't get it working, you can tie the ign wire into your accessory wire at your ignition harness, or your cigarette lighter if it's a switched power source which I can't remember if an f150 would be constant or not..

do you know where i can get a fuse diagram i dont have the owners manual anymore.

Most are directly on the fuse panel cover.

How are you checking the fuses? If you have a multimeter than can test continuity it'll take literally 60 seconds to check'em all.

did you check the fuse box under the hood as well? that is where my constant fuse is.
