If anyone can help me out here, I'd really appreciate it - here's the deal...i bought a 97 Civic LX used, with an aftermarket HU already in it. I wanted OEM keyless so i bought an ebay radio from a 96 LX, Metra Harness, and keyless remote. I wired the harness and connected it to the Honda radio, and the aftermarket radio, then connected the famous Green plug to the Honda radio. The aftermarket radio works fine, and the Honda radio powers up as well (although no sound since speakers aren't wired). When I go to program the remote, and push the "valet/prog" button on the honda radio, the locks are supposed to "cycle", but instead nothing happens. Is there any way anyone knows of to tell whether the radio has something wrong with it or if the wiring in the car has been compromised? Like a pin-out or expected readings from the pins or the harnesses from a good manual? Thanks in advance.
