AUX SWITCH WIRING QUESTION

[bigblackbronco]

HELLO OFF ROADERS, thanks in advance for your help answering my newbie wiring question

Correct me if I’m wrong, my understanding is that the ford bronco aux switch wiring includes the fuse and relay in the power distribution box.
So my question is, in order to wire AUXBEAM ditch lights , can I cut into the wiring harness provided by AUXBEAM between the 3pin DT plug and the automotive relay to expose the power and ground wires ? In theory So I can splice the ground and power wires directly to the bronco aux switch wiring which already has a fuse and relay, bypassing the redundant fuse and relay in the aux beam wiring harness ? Any and all advice appreciated .

Correct. Just make sure you connect the power wire to the Aux wire that can safely handle 168W

Switch(s), you have (2) sets of lights.
White and amber.
While you could put them both ono a single aux switch, I am not sure that would be the wisest choice.

Yes, you're correct.
Also, if you want to save a switch, you can use a fuse tap & hit Fuse 24 to have your backlit DRL on at all times.

This what I did but used this...

I used the diode dynamics harness that came with mine & I already had a fuse tap on 24 from my Grill letters, so I just spliced my backlight into that harness. Cheap & simple.

Can you elaborate on this ? Newbie here who is trying his best to understand what you mean.

can you explain why you don’t think it’s a good idea ? I completely forgot it has amber DRL lights … does that mean the wiring harness has two sets of wires that I can cut into to connect to the ford aux switches ?

The fixtures, light pods, you have have two sets of LED diodes.
The connector has three wires
Two switch legs shared ground
If it were me, I would connect one switched leg to a uplifter switch individually

If not, you have a white and yellow light on at the same time.
Seems like a mistake, in my opinion.

Thanks for clarifying ! I think I’ll take your advice

If I’m understanding you correctly are you saying I should run the AMBER DRL constantly while the car is running ? Isn’t that illegal in California ? Where I live

In fact, I did not say that.
I'm saying you should connect each set of lights to its own uplifter switch

Let me clarify, Amber lights should turn on aux. 1, white lights aux 2
(I'm not saying specifically use those aux switches, just listing them out for clarity)

I have no clue what's legal in CA. I'm in PA. No one has bothered me with mine for over a year.
But you can get what's called a fuse tap, which is essentially a replacement fuse with a wire running out of it & make your connection to that for the amber DRL.

If you replace fuse #24 with that, your Amber DRL will run anytime your vehicle is turned on.

There is a difference between an
Amber backlight, and the main LED light

Backlighting is very low power. It won’t light up the road. Also fine to run it at the same time as the main LED, you can’t see it as the main LED will be thousands of times brighter, but it won’t hurt anything either.

Some lamps may have two main LED lights - I’ve not seen one though.

With regard to legality - CA does allow backlighting but they must meet some standards on installation height and color. They are considered a Running Light (like DRLs). For most installations they are perfectly fine
