I routed the wiring using a existing hole that other electrical passed through. (Right above the radiator in the picture.) I used the existing speed pickup and control from the Dana unit. The power was taken from the buss in front of the steering column that is switched by the ignition switch.

This unit works very well. Installation took about 5 hours from start to road test. I did have to adjust the slack to prevent disengagement at full throttle.
