I think I can get it pointing directly at the cable mounts.



Since it has built in limit switches I think a bi directional DC toggle switch is the plan. Hold in place until it stops. I would then use a separate 12v and put a proximity sensor on the shaft so when it's retracted and open it sends 12v to the parking brake light on the dash. Will run that trough a relay so it's only on when the car is on. Nothing is a done deal but I am very encouraged so far.
Rather than relying on the limit switch to provide correct tension on the hand brake cables, you could use a current sensing relay to measure the motor current (torque) applied to the cables. This could be used to shut off the linear actuator. This way you would always have the correct tension applied to the brake cables. Something like this:

I can help you with a wiring diagram if you like. I think it would be a cool solution.
