Question:
I have a Ford E450 forester, Im trying to install my Tekonsha 3034. The plug is the same but the wires aren’t. They don’t align with the camper plug. Can you help me line these up? TIA

Expert Reply:
Phillip, if the wiring on your Ford E450 doesn't match the Tekonsha Plug-In Wiring Adapter # 3034-P, which is designed for the port on an E450 cutaway with the factory installed 7 Way, then the only way to know will be to test them for function.
You might be able to contact a Ford dealer to see if they can tell you which color handles which function. On the controllers we carry, the white wire will be the ground, the red will be the stop light/brake switch, the blue will be the brake controller output, and the black will be 12 volt power.
