Garage Door Opener - Stealth install

An add-on to my post regading the switch buttons.

First of all, it's a standard 3-button Sears door opener. I removed the console switch array looking for a place to conceal this opener, and found there was a fair amount of room under this area by the parking brake.
I modified the Sears opener to include a cable from the main push button, and a cable to a circuit for the voltage reducer circuit.

I also had to build a small converter circuit (shown on the right in the pic) to drop the +13.5V (actual) to +3V for the opener.
This circuit is easy to build and provides a variable DC voltage for many in-car devices. The circuit when properly sinked with a heat sink, can deliver 1.5 A of DC Voltage.
I also extended the length of the antenna of the door opener itself, to compensate for concealing the door opener button. This works well.

I ran a separate constant +12V cable from the fuse box, under the center console to this area. You could tap into the door lock switch circuit, as there is +12V available there, but that is 'switched' power. I took apart the opener, and wired a small push button to the opener section.

I mounted the modified circuit boards into a small plastic box.

It snaps back into the console bezel, and then you can wire it to the power wires you ran back to this are.
