A number of videos ago I took a final drive in the 1990 Chevrolet Cavalier.  In the early 2000's, I had installed an alarm system/keyless entry system in it.  This also included installing door lock actuators so they could be powered, plus all the wiring to do so.

I had purchased this unit from Parts Express, along with the relays and door lock actuators, also a trunk actuator.

Now that xjoe81x has a new garage door, he still has the old, vintage opener.  That's all fine and good, since it's vintage and works well.  The only problem was the remote for it didn't work.  It turns out the opener is very simple.  There are 2 terminals on the back of the motor.  When they are shorted across for a short time, the door will either open or close, depending on its current state.

Since the Cavalier was scrapped, all the goodies including this system were removed.  It was then that I remembered I had it, and that it can be used to power a relay, which, in turn, will short 2 contacts together for a short time.  Thus the idea to convert a car alarm to a garage door opener came about.  This part is basically sorting out the wiring.  There are quite a few wires that must be contended with.  Of course I had to also supply the relay and the power supply for this project, as well as the system itself.
