First of all, it's a standard 3-button Sears door opener. I was looking for a place to conceal this opener, and I opened all the small plastic panels I could on the console. I finally opened the switch panel in the center console, and found there was a fair amount of room under this. I ran a separate +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. I took apart the opener, and wired a small push button switch to the opener section. I also had to build a small converter circuit to drop the +13.5V (actual) to +3V for the opener. I wrapped them both in electrical tape, and carefully pushed them back into the space. I pushed them to the far side of the area under this set of switches.
I extended the length of the antenna to the door opener itself, to compensate for concealing the door opener button. This works well.
