What gauge wiring to the aux switches?

As topic states. Thanks!

I found this one helpful.

Factory Aux switches have different size wires than the Aux kit that you or the dealer installs.

I believe the factory install, has 12 awg on the 40 A switches, and about 16 awg on the 15 amp switches. In the passenger footwell, the 10 amp, direct to battery and ignition on wires are smaller, perhaps 18 awg or less.

What are you trying to figure out?

Im going to wire up some lights and just need to know what gauge deutsch connectors to get. ?

Thoughts?

I have my two KC on switch 3. How many lights are you running? What kind of draw will they have? I don't see my two LEDs running over the 15.

 

[KurtP]

2 sets of 3” diode dynamics pods, each pod drawing 3 amps at 12.8v. They should be able to go to the low draw switches.

Easily on the 3 and 4.

@DocMike @Pepe so that would mean a 16gauge D connector fitting, correct?

I could be wrong, but I think it is all about the amps. I can tell you I made the mistake of not reading the max amp draw under load, not just amp draw on my compressor and had to wire twice based on the amp draw, maybe if in doubt go heavy based on the max the aux switch will handle in case you want to go with something else or more amps on that switch, most wire gauge ratings are based on amps I believe. Something like this (chart mid way down):

Youre not wrong, but I cant see diode dynamics pods breaking 15 amps. The 3” light pods i put on my KTM dont break 10 at full power, so it should be fine on the low draw. I just neded to know wha gauge the wires were for it.

A little more precision in the chart at the lower amp ratings.

AWG chart

And remember your length is from the source (battery) to the load and back to the source.

Solid dope. Thanks.

10AWG for 15A at 15 feet?
A bit pessimistic, me thinks.

And I wouldn't worry too much about the return length, as you'll be grounding to the chassis, and it'll handle plenty of current. Just figure in the length of the ground wire.

Based on what @Pepe posted, yes. And I used the grounding block in the engine bay like in the video. Crazy easy.

Are these the halogen daylighters or LED? I just bought the halogens for my Gladiator and I am on the fence about changing the fuse out to 20A since the two lights add up to 16.6A.

LED for mine. Crazy effective.
