Just purchased the Prodigy (Tekonsha) from rjays.com with the pigtail and extra wiring.
My problem is I don't have the wiring going to the back. The plug is under the dash (light blue 4 prongs) and there is a 40amp fuse in the box where the elec brake is.
When I wire it where do I splice into? If there is a fuse in the box is there a plug ? and if so I can't find it anywhere. I bought this truck used. There are two screw holes where the controler should have been on the dash and I know they had some kind of 5er on the bed with the holes and brackets on the frame but no wires to the back or anywhere.
Help!
