Battey is red and RED / white at ignition switch.
Ignition is pink; Starter is yellow or sometimes purple.
Accessory is orange for the heater.
Parking lights are brown at light switch harness.
Brakeswitch is white at brake.
Tach is PURPLE / white at coil pack on engine.
Doorlocks are positive pulse. Lock is light blue and unlock is either white or black in either kick panel. The power trunk release wire is usually a high current black wire at the switch. Use a relay to activate this.
