Adding extension switch to steering wheel that operates factory AUX switch

[Robellion]

Hi all-

Anyone ever do this? I have Mopar lights on the cowl that are in bank 3 and another set on the bull bar operating out of bank 4. I often drive on a very dark road with lots of deer and find that using the off road lights really help me avoid accidents with those animals. I am aware that they would blind on-coming traffic, so I was thinking it would be great to have the switch extended to the steering wheel area so I can switch them off on the fly instead of hunching over with my finders near the factory AUX switch location.

Would anyone know what to buy or have you actually done this? Can a existing button on the steering wheel be connected for this purpose?
Thanks so much

HAPPY NEW YEAR!
Eric

I can not help you with the steering wheel switch option, but I can suggest you run the aux lighting through a relay that utilizes the bright light circuit as the trigger. That way when you dim your brights it automatically shuts off the aux lighting.

Hey thank you- so you are talking about setting it up so every time you switch on the brights, the Mopar lights come on (whichever I choose according to which AUX bank I connect), then while switching back to regular beams the Mopar lights come off?

That sounds like what he's suggesting. You could take it a step further and power the relay from your aux switch, then use the bright light wire as the relay trigger. This way the auxiliary lights would only run if you turned them on via the aux switch, but once you do that they would cycle on and off with your bright lights.

Yep Dan, that is what I did. I utilized this thread to identify the tap point.

Gotcha! Reading it again I see that now. Still early after a very late night! ?

This is how I have my ram truck setup, it works great as you can run just high beams or highs and lightbar. Cool thing is with the auto feature the lights will dim when it senses an oncoming vehicle. (Although sometimes road side signs will trigger it with the lightbar on).
I bought the jeep used and the previous owner wired the light bar to the fogs as there's no fogs on the replacement bumper. Its not very convenient to grab the fog switch vs the high beams switch, so ill probably re-wire that in a similar manner to be trigger by the high beams.

Ok- gotcha. That sounds like a great set-up. So when someone else (like my wife) is driving, they would have the normal low beam/high beam functions unless they knew to press the AUX bank 3 or 4- whichever I decide to wire up to have a low beam/cowl light beam function. Brilliant! Thank you everyone for chiming in.

Great ideas.
