GEN 2 Wiring Upfitter switches

[smurfslayer]

There are two wire bundles.

2nd place I’ve seen this. I spent 30 minutes under the hood, Lucile has 1, and only 1 bundle. With luck I won’t need to hit up a dealer any time soon but when I do, I’ll ask them to figure it out.

That is not how it works. Where is your ground? the one set is simply pass through wires back into the cab. The so called 'hot' side is controlled by the upfitter switch through a relay.


Raptor Supplement to that Owner's Manual thing, page 44:

AUXILIARY SWITCHES
The auxiliary switchboard on the overhead console makes aftermarket customization easier, with six prewired switches attached to the power distribution box for electrical accessories.

These switches are labeled AUX 1, AUX 2, AUX 3, AUX 4, AUX 5 and AUX 6.

They will only operate while the ignition is in the on position, whether the engine is running or not. It is, however, recommended that the engine remain running to maintain a battery charge when using the switches for an extended duration or higher current draws.

When switched on by the operator they provide electrical battery power for a variety of uses. The switches control relays and fuses that are under the hood in the power distribution box.

The Aux switch powered circuits are found as blunt-cut sealed wires, located by the power distribution box.

There will also be one Aux Switch pass through circuit for each switch found as a wire located to the right of the glove box door and just above the passenger-side kick panel. You may need to pull down the auxiliary cords to access them. Refer to the Fuses chapter of your Owner’s Manual for information on fuse and relay locations.

See your authorized dealer for service. Additional pass through circuits that run through the dash panel and under the hood, are located in the same location.

Accessories
The relays are coded as follows:
Fuse Wire color Circuit number Switch
15A Green/Blue CBB47A AUX 1
15A Gray/Yellow CBB48A AUX 2
10A Violet/Orange CBB94 AUX 3
10A Brown/Blue CBB96 AUX 4
5A Gray/Orange CBB98A AUX 5
5A Yellow/Violet CBBA0B AUX 6

Still dont understand. So there is a bundle of wires behind the battery that is taped up butt end joints. Do I not just connect the LEDs to two of those and thats it? Im not understanding how this works.

Ok, first off, what lights are you trying to hook up? For the sake of discussion we will assume a 2 wire setup like the square pod lights (BD squadron, rigid dually). The one set of upfitter wires is switched 12vdc from the upfitter switch, through a relay. That connects to the red wire (+). The black wire goes to chassis ground (-). Depending on what particular light you have there may be a third wire for the special feature. That will need another 12vdc input or ground through a switch depending on the light and the specific feature, consult your light manufacturer.

There are two bundles of 6 wires each in the engine bay, the bundle that is closest to the battery tray is "hot" when the engine is on and you flip the corresponding upfitter switch in the cabin. The second bundle is a bit further away from the battery and closer to the firewall, these are pass through wires into the cabin and are located on the footwell under the glove compartment; you splice the corresponding wire from the first bundle (i.e. black/yellow to black/yellow) to the second bundle and thus transfer the power into the cabin.

If you are wiring lights you would wire your positive wire to one of the wires on the "hot" bundle (closest to the battery) and the negative wire from the lights to ground. Be careful with the amperage of what you are wiring to the upfitters.

If you have never wired LED's or any other electronic auto accessories, may I kindly suggest you hire a professional to do it. I mean do you really wan't to learn on a 60k+ vehicle and potentially create a hazard?

So just to be clear, you would use the first bundle if you want to wire up something outside the cab like a LED light bar to an AUX switch and the second bundle if you want to wire up an espresso machine inside the cab to an AUX switch?

I have installed lots of non LED lights, several radios, speakers, amps...that sort of thing. Just never used a factory aux switch or an LED light bar.

Those should be 2 wire, positive to the upfitter wire, ground to chassis.

Yes, for example in the engine bay I have Switch 1 green blue wired to three pairs of Rigid D Series in the fog light opening with n-fab brackets, Switch 2 gray blue running all the way back to the rear bumper to power a pair of Rigid Ignite backup lights (yes 15A is overkill so I replaced the fuse because I wanted the two lights next to each other since I am OCD), Switch 3 violet orange to the Power Interrupt Solenoid on the WARN Rear Quick Connect which I use for the ARB Dual Portable compressor. Switch 4 brown/blue is empty. Then 5 gray orange and 6 yellow violet are spliced into the cabin for the radar detector and dash cam respectively although I ended up connecting the V1 via Savvy so it's not so annoying around town.

Didn't mean any offense, just making sure because there have been cases of people damaging electronics for lack of experience.

so I just checked the Blue/Green wire (aux 1) with voltmeter engine on/aux 1 on and I was getting voltage in the engine bay...so if this LED is a two wire this is going to be a simple installation...just T tap into the Blue/green and then the ground wire.
