Can someone steer me in the right direction ? I bought a nice Pioneer double din unit that came with the wiring harness and antenna adaptor. I removed my stock delco unit which appears to not be a Bose and the harness does not match and there was no antenna connection to the radio so I am obviously missing something here right ?There are 2 plug connectors in the dash, one with 7 wires and the other with 9. They sent a Metra 70-1858 which says it does a Corvette but ?
