Could an existing Tremor owner please elaborate on the wiring/fuse setup for the panel (or lack thereof), with pics if possible? Is there a control box in the engine bay?

Also, please describe your intended use for the switches.

The 'panel' is located in the engine bay drivers side. You will see a black box (mine was wrapped half-assed) in black tape...it has the relays and fuses with leads out the bottom of the box for direct wiring. Don't have a wiring diagram yet, but did see one somewhere on the forum...i'll post if I find it.

Thank you, I've recently watched a video of the new Bronco Aux switch wiring setup - it already has the factory wire runs to few strategic places on the truck. I was hoping for the same to be true on the Tremor but alas, it appears to be not as well thought out/implemented on the Tremor.

Have you been able to figure out how to get to the bottom to wire something in? I find the wiring already ran though to be very tight. I see where the new wiring is to go into the box, but the box itself is not easy to access the bottom.

Anybody have a picture of the wire color and amp table from their owner's manual?

Well that is definitely settled then, the NA and Australian are wired differently.

I don't see by the pictures were the incoming wiring is allowed to connect yo the block. Even if the wires are different, can you please explain where the new leads are to go?

@overanger has a picture with his hand showing a small bundle of wires, these are the 6 seperate auxiliary outputs. Separating the bundle will reveal the individual wire colours (each circuit).

When a upfitter switch is turned on, 12v will be available on its respective circuit via a fuse and a relay. To quote from @Overangers manual, Switch 1 is a 25Amp supply connected to the yellow wire.

If you wanted to connect a set of spotlights for example, the positive wire of the lights could connect to the yellow wire and the negative wire to the chassis. These lights would then be controlled by upfitter switch 1 - as long as you respected the maximum current draw.
