Chevy Cavalier 1997 Aftermarket Radio

Hi, just installed an aftermarket radio to replace the oem in my Chevy Cavalier 1997. My speedometer and odometer doesnt work anymore, with some search, i saw that a vss wire passed through the old connector. Something linked with passlock ? What to do !

Check your wiring at the radio. The VSS wire is at the radio if you had an upscale cassette or CD radio. The VSS wire is GREEN / WHITE. Make sure that it is not hooked to anything and is taped off. Double check all other wires as some duplicate colors are used. The wrong wire can fry your radio as they are for lamp circuits and not speaker wires. This is why an adaptor plug should always be used unless you have done many before.sparky
