OEM Aux Switches

[SmokeyJoe101]

I just installed some lights and hooked them using the Aux Switches. I used a relay, after realizing how small of gauge the wires are for the Aux Switches. The wires look way too small to handle 40A and 15A.

Has anybody tried 40 or 15 on those switched wires?

40 amps? What kind of lights are you trying to hook up?

Sorry I was not clear. The lights I hooked up only pull 22A.
I was referring to the ratings for Aux 1 being 40A and the gauge of the wire provided in the wiring harness seems to small for 40A

With the factory AUX switches, you don’t need to add an additional relay since that’s built into the system already. Only time you need an additional relay is if you are running a light that has a high/low beam.

The wires for the 40 amp are plenty in the system. In case you need it;

I guess that’s the question at least for me. Those wires look like 14AWG, that does not seem large enough for 40A. The others look like 16 maybe 18AWG and also seem too small to handle 15A.
Also if you go with the same gauge wire as provided in the Jeep and extend that to the front for light your adding another 8” of wire.

I don’t know I went with 10AWG and I know I am more than good for 22A.
