Hell my new one cost 400 I think. And I still use the 5 dollar one sometimes

On my way to walmart to get one now. I think I may need to just tap into another hot wire.

I figured it out, the ignition wire on the aftermarket wiring harness goes to nothing. So If I hook it up to the constant power I'll just have to remember to turn it off. Only problem is there is no power button on the head unit and the remote for it doesn't work for some reason. So I have to find a keyed hot wire, this is really becoming a pain in the ass.

Also the right rear speaker doesnt work for some unknown reason, it worked just fine with the factory head unit.

The other plug is likely for for option items like a sync, subwoofer, rear seat entertainment, auxiliary devices, etc.

The reason you won't find +12v from the factory radio harness is because the computer/BUS has it ground relay switched internally in the factory radio.

You just need to search out an ignition source with a test light and tap on.

Those pins on the aftermarket harnesses aren't always seated and can get pushed up instead of in.
