I hope it's not just a software glitch, but I was sure my Prodigy will apply the trailer brakes if I step on the truck brakes while touching something on the controller... I tested the features after installation (a year ago), but the instruction card doesn't mention it?

Otherwise, I might need an EE to help me hotwire that baby to do what I want!

 

You could just yank the pin on your breakaway safety device, but as mentioned, probably end up with a dead battery...
