Auxillary switch wiring connection/distribution panel?

[nolimits]

The other plus is making all six switches 30A instead of 1 30A, 1 20A and 4 15A. So if you have an accessory that draws 25A you don’t have to put it on switch number 1 you can put it on any of them.

Doing some other electrical work and was considering adding a terminal block of sorts for future ease.

This device raises a new question. What is the wiring size of all the factory ran wires?

I believe from the switches to the firewall is 18 AWG for AUX 2-5 and 16 AWG for AUX 1. However, I am not certain about from the firewall to the rear, windshield, bumper, etc.

I’m guessing the amp pull from the aux switches to the RC device is minimal so wiring size is inconsequential on that part of the leg.

What concerns me is depending on the wire size from the firewall to each “convenience location” may factor into the ability to run more amps. Even though the RC device may be able to handle it, the wires needs to be sized accordingly for load and distance so they don’t overheat and potentially create a fire risk.

Obviously I haven’t done a deep dive. Just heard many gripe about the wires being undersized (generally, not specific to this RC device setup) so it got me curious.

I have not used any of the factory pre run wires so I can’t comment on that but depending on what you are running they would probably be undersized even connected to the aux switch wiring. Like you I think the draw on the aux switch wiring will be minimal considering I’m simply using them to activate a relay. I would definitely run my own wires for anything other than a small LED light. I just like the convenience of having a terminal block to connect to and the fact that if I want to change what’s on each switch it’s as simple as using a screwdriver to change terminals.

From the Equipment Install Guide.

Everything on the Bronco is metric obviously... but...

• 1.5 mm2 is roughly 15 AWG
• 0.75 mm2 is roughly 18 AWG

Appreciate the additional feedback.

I looked at the install instructions and didn’t see where RC clearly stated what the amp draw was on the AUX switches themselves. Generally speaking their install instructions start with disclaimers which I read as them being skiddish, yet they state to contact them with any questions.

In contrast I am about to wire up my winch and a 500 amp relay so I can kill power to the winch when not in use. The relay will be triggered on/off by an AUX switch. The install instructions are very clear about the amp draw for that device, which is 1 amp or less.

It seems the RC device works in a similar fashion, I just wish RC was more detailed & clear about it.

Perfect, thank you. Weird they used 15 gauge wiring. Not sure I’ve ever seen that.

Yeah it's not actually 15 AWG. It's just metric wiring.

15 AWG is just the closest American Wire Guage size for a 1.5 mm2 metric wire. Although... I guess it's actually somewhere between 15 AWG and 16 AWG.

• 15 AWG = 1.6502 mm2
• 16 AWG = 1.3087 mm2

this is what i did, works great.

grounds for all my various lights are just at grounding points on the vehicle.

FWIW, I opted to use some weather packs. I just ordered yesterday and they shipped out but I haven’t gotten them yet. Much cheaper to make up your own, just a couple bucks each.

It doesn’t “upsize” the amperage like the RC unit @Dover157 used, but when/if I need that in the future I will address then. In the case of my winch I already have a dedicated relay that does up to 500a.
