I am installing a keyless entry-remote start on a 96 chevy lumina, on the three pin connector for the door lock I have the two lock and unlock wires connected, but my instructions do not show me where to hook up the third wire (red 12V+ Out), can anyone help me out?

Thanks, Steve

The third wire is usually fo the relay. You only need this wire if you have positive door lock type, reverse, vacumm...etc that need to be connect to a relay(s). IF you have standard negative door lock type, you only need the lock and unlock wires.
