Thanks, you were right, had to hack off the whole crimp connector since there was zero chance the thick controller wires would go in even after snipping off the tubing. I did the 'western union' join and some solder but my soldering skills do leave a lot to be desired, although I'd like to blame my lame-o soldering iron.

Cool. My controller is a REESE 'POD' controller but I also found it's made by a company named Tekonsha.
