1989 honda crx
connecting kenwood kdc-mp245
have to hardwire into car, no harness
have the speaker and ground connections figured out.
I need to know which connection goes where: connect the (Battery/YELLOW) wire and (Ignition/RED) wire INTO either the (RED/YELLOW Main stereo supply/radio switched 12v+) or the (WHITE/GREEN Constant power 12v+).
