Has anyone used one of these? I bought one off Amazon.ca to play around with but I can't find how to program it anywhere. Of course it came with no paperwork at all!

I've never used one of those, but looking at the pictures and reading the description (quite a poor translation), it appears to work as follows:
Hook up:
12VDC input is supplied to the 2 position green terminal. Polarity is shown on the PCB silkscreen on the bottom of the PC Board. The output appears to be a set of relay contacts on the 3 position green terminal, with contact locations silk screened on the PC Board: Normally Closed (NC-equivalent to pin 87A), Common (Com-equivalent to pin 30), and Normally Open (NO-equivalent to pin 87). Look at the 12Volt.com relay section for more detail.
Operation:
The relay is controlled by the included remote. It can be used in 1 of 3 modes: jog/unlocked, Interlock/Lock, Auto Lock/Auto Lock
It appears that the modes operate as follows:
Jogging/unlocking, press and hold a button to activate the relay, release the same button to deactivate the relay. (Channel switching requires a remote control button)
Auto lock: momentarily press a button to activate the relay, momentarily press the same button to deactivate the relay. (Channel switching requires a remote control button)
Interlock/Lock: Press one button to activate the relay, press another button to deactivate the relay. (One channel change requires 2 remote buttons)
Remote Programming:
1. Learning method: Press and hold the learning code button on the PC Board for 3 seconds. The indicator light will go out, then release the learning code button. Press any button on the remote control to send a signal, the indicator will flash 3 times, and then the method of learning success will be displayed normally.
2. Delete/Clear Method: Press the Learn button for about 8 seconds, the indicator will remain off, indicating that your saved information has been successfully deleted.
This is my best guess. Experiment with it and see what you find.
