What are these unterminated wires under the hood?

[Steve o]

I was wiring up my new Auxbeam 8 button rgb switches. I noticed that just above the firewall gromet where the main electrical passes thru, are several wires unterminated. They are heatshirked at the end, but don't go to any harness. They are tied to large wireloom. They are nearest to the driver side hood hinge. What are they for?

Without seeing what you’re looking at, pretty sure they’re the leads for your Upfitter Switches.

Aux switches like Baja Bronco said.

So the other end of these wires would be inside the cavity where the Sungalsses holder currently is? (I don't have the factory AUX switch bank).

No, those would terminate at the plug near or into the fuse / power distribution box under the hood.

For the flux capacitor.

While we’re talking about those wires… Can someone post the schematic of which wire goes to which up fitter switch and also the other wires that go forward and to the rear. Or point to a thread here. Hooking up lights today.

If there are 6 ends, it's the aux pre run wires. But you are probably missing the fuse panel and actual switches

Aux switches prewired. Used these to connect my fog lights, pretty amazing really.

For the flux capacitor.

By the Slausson cutoff

For the flux capacitor.

Sorry, that's a constrained item. If yours is showing already produced, it's sitting at the Twin Pines Mall awaiting installation once the Flux Capacitor arrives.

IIRC these travel into the harness, and travel up to the connector inside the base of the A-pillar. If your bronco didn't ship with AUX switches you need to install a new A-pillar harness to bring the wires from their current position (bottom connector for A-pillar) up to the center pod where the switches install.

It still blows my mind how many Broncos were ordered without the AUX switches. It’s one of the few bargain options.
