Non Motorcraft 7.3 GP Controllers?

The 6.9 style is pretty easy too. Just run a fused power wire to your push button. Then run it to the terminal that the purple wire attaches to on the fender mounted relay. I just cut the end off of the purple wire and splice my power wire into it. That way it pushes onto the terminal like the factory wire does.

Yeah, I guess my method makes sense if you want the controller itself.

I don't have my controller any more. I plugged the port. It's different for my 6.9 style vs your 7.3 style. Your relay is mounted to the controller where mine are separate.
