It is highly doubtful you screwed up the programming as it is "hard coded" into the PIC. The F-14 expansion modules with the exception of the proportional channels, uses the outer two wires of the servo type connectors as switches to ground. The center wire is power if you need it. When you flip a switch on your transmitter one way, one wire will have ground. Flip the switch the other way and it's the other wire that is now ground, center is off. There is a jumper wire in the expansion module that determines if the momentary switches will "latch", that is act as a somewhat permanent on/off switch. If you use a momentary switch and the jumper is installed, when you flip the momentary switch the first time you get your ground connection. You must flip the switch a second time to turn it off.
