Dan,

I never even heard of them before. I am just now getting into street rod stuff after doing Vettes and others for most of my mechanical life.

The concept is simple enough. Making sure it is in the right gear is the trick.

I thought about this yesterday in the shower (do some of my best thinking there).

If I run the main power (it does not draw many amps at all) through the brake light switch, then there would be no way to change gears unless the brake was activited. That would keep you from popping it into reverse or something while going down the road.

Second, I thought of going to the bone yard and finding an old cable operated gear shift indicator for a '70s-late '80s car. You know what I mean, the spring loaded PRND21 clear plate that the orange needle could be pulled across. Then, I would have to mount the cable on the shifter and mount the indicator on the column or somewhere. After I figured out how to synch the two, I would know what gear I was in at a glance. This way I would not have to put any sort of limit switch for each gear stop.

I already have the actuator motor and bulk wires to put the electric together, I just need to polish off the details here.
