Re: 93 probe radio Wiring
hey. the probes hav a stock amp in them.and in order to use an aftermarket deck, u need to bypass the stock amp with a bypass wirering kit, u just simply unbolt the amp.(i think its 3 bolts), unplug the wire connecter going into the amp to one end of the harness, and the other end, to the out of the amp, the amp is located right under the rear passenger speaker. u will need to remove the paneling to get to it.if this is not done, u will not have any sound at all. im not really sure what u meen by the grounding question , but if u hav any other questions, just say , and ill try to help.
