i just got a dodge and it has wires in the back just laying around from where the speakers use to be and the man also said he had taken out a plug which he gave to me. it says bus on it, is orange, and has two prings on it. last night when i was driving home everything went crazy. my interior lights were flashing, my abs airbag lights came on and it said no bus, all my gages dropped the zero and eventually my lights went out all together. my car was still able to drive and i made it home but everything was still going nuts! is it because of the wires in the back and the fact that the plug isnt in where it should be? i tapped up the wires, but where does that plug go? someone please help.
