Never mind. I couldn't resist.
OK, so I found an old 2pin sensor (female) cable end, and connected it to the two lower right hand pins. The one labeled "2"(RED?), and the one nest to it which I am assuming is 4 (Yellow?)
Anyway it worked. I was able to program code 1 with a button on my cheap DVD remote.
As for the Sensor part.... I will assume you connect them to old PWM cables. However I could be wrong, so I'll wait to hear otherwise.
