2nd Ignition - BLACK / YELLOW - igniton harness
Accessory - blue/red -igniton harness
Power Lock - WHITE/ green - DKP or door harness (meter this wire while urning key in driver key cylinder)
Power Unlock - blue/white - DKP or door harness (Meter these wires while turning the key in the driver door key cylinder. Unlock requires a double pulse)

Tach wire - black or blue/white - instrument cluster, brown plug. (It is black on the 6 cylinder models, and blue/white on the 8 cylinder models, at the instrument cluster.
On the 6 cylinder models the black wire is also found on the driver side of the motor at the diagnostic connector. On the 4.7L V8 can also use BLACK/ blue at coil 1 on the driver side.)
Brake wire - GREEN / WHITE - brake pedal switch
