In Depth Instructions on the Upfitter Switches?

[HaZeMySt]

I wired up some lights behind my grill... But I am lost on how to wire them up to the upfitter switches... Does anybody have pictures (not the ones ford gives) on how to install? I can't find any useful instructions.

Also, are the AUX switches supposed to light up when you flip them up, wired to lights or not? Thanks.

Its pretty easy. There are four blunt cut wires to the left of your steering shaft under the dash. Those are your four hot wires from the switches. The owners manual tells you what color wires they are and also what amp they are. They come from the factory taped to the main electrial harness which runs through the fire wall, but you'll have to look closely because there is a bundle of other blunt cut wires there also which containts alot more than the four you will be looking for.

There are a lot of threads on here about this.

1st thing to find is the upfitter power wires, they are above and left of the steering column, mine were actually taped on top of the harness and could not be seen by just looking up from the pedal area.

2nd thing is locating the pass thru wires, they are in the wire bundle at the emergency brake pedal assembly. And are under the hood, drivers side by the hood hinge on the firewall. There is good info on these in the owners manual too.

3rd thing, splice an upfitter wire to a pass thru wire, I used a short piece of wire between the two, but if you have really skinny arms and can stand on your head for extended periods you may be able to get the two together... all the colors and such are listed in the owners manual.

4th, wire the positive lead from your lights to the pass thru wire at the firewall and ground the other.

should be good to go...

Mine was a little more complicated, but if you have a pair of 35W or 55W lights this will cover you, use one of the 30amp switches, your owners manual will tell you wich color it is.

With the wiring harness, and cover plate, you're sitting at just over that and that's from Tasca Parts. Don't even want to think about what they'd cost in Canada from the dealership.

Ridiculous.....as usual.
