Did some upgrades to my TV.
Added dual input rear view mirror with digital video display and bluetooth.
Added a Bluetooth OBDII scanner so I can monitor my 6.0.
Put some switches on my dash. Upper left is a SPDT rocker switch that allows me to choose which to display on my rear view mirror. My backup camera on my TV or rear camera on the camper.
Lower left is the on/off rocker switch that cuts power to my OBDII device so it will not be drawing power when parked for a long time.
Red button... Self destruct of course!
Naw, just hooked up a momentary switch to my garage door opener. Since the opener used a 12v battery, I wired it to an ignition power source and soldered wires from the switch across the momentary on the circuit board of the remote. I put in the overhead and out of view.
