Liftgate actuator wire routing

Does anyone have a digram or information on the routing of the liftgate actuator wiring on a 2000 Cherokee. Liftgate actuator stopped working, actuator is good, bench tested. Probing the wiring with a power probe III, I get + 12volt on the pink/black trace both in lock and unlock. No voltage or power or ground indication on the orange/black stripe.
Thanks,
Bill

Don't know anything about the physical wiring, but...............
