For those with prewired aux. Can you help me sort out my rigid ditch light wires. So I think I will use the lo pigtail in the engine bay for this. Do I discard the battery part of the wiring and just attach the wire from the ditch light straight to the pigtail?

First, you need to understand the amp draw from the lights. Then you simply run the appropriate guage wire from the lights. There will only be a positive and ground. The ground can be wired directly to any ground spot in the engine bay. You run the positives to the power source. If using an aux switch to direct connect to the ditch lights, make sure you pick the proper switch with the correct amp rating.
If using the switch to power a relay, then use the lowest amp rated one (aux 3 or 4)

Here is my Arb compressor install video that discusses aux wiring in depth and I use the aux switch to trigger the unit to turn on. Then it uses the direct connection to the battery to power on. Not ditch lights but hopefully this helps.

@4Rghostpro I'm trying to do the same as you, planning on two Diode C2 2.0 pods as ditch lights and want to hook them up to an AUX switch. Did you get them hooked up and working?

This helped me a ton and appreciate the video for visuals.

I've never hooked up lights before and I would love a second set of eyes to confirm my plan before I order parts if anyone feels like taking a look or has input, I messaged Diode Dynamics about their recommendation and it seems like overkill to me but here's my plan...

Combined the main beams of the pods would be 3.6A (1.8ea) and the backlight of the pods is 0.0
6A (0.03ea). I was hoping to hook the main beams up to AUX3 and the backlights up to AUX5 to be constant on ignition (both of which should be plenty to power them). To do so I am HOPING to run:
- pod wiring harness from pods to the aux "LO" pigtail in engine bay
- connect pod positive wire to the BLACK pigtail wire (AUX3)
- connect pod backlight wire to WHITE pigtail wire (AUX5)
- connect pod ground to either the pigtail BLACK/WHITE STRIPED wire or another ground spot in the bay.
And that's it right?

I ask because Diode recommended their "HD" harness since it includes an "upfitter connector" like so (B):

My confusion is that they said "unless you have a custom harness made elsewhere" it still would require being powered by the battery and keeping the relay (like your compressor). That seems like excessive wiring to me for the lights when the AUX system could power them by itself.
I feel like I could cut their harness to go straight from"C" to the AUX pigtail and call it a day but am I totally off base?

Thanks for the help!

Your diagram is really complicated. Is there a reason for complicating it or do you simply want a switch to run the lights when the Ignition is on?

if so, (assuming proper wire guage) run the positive from the lights to the aux pigtail positive wire for the switch you want. Run the ground to any nearest ground point on the car or run it to the ground wire of the aux pigtale. Very simple. Good luck!

if you want to test your circuit, use a multimeter and put the geound where you want to ground and the red on the proper aux pigtail wire. If you get 12v when the switch is on and nothing when the switch is off, you know the circuit is good and you just have to run the wires.

Thanks for taking a look at it, and I totally agree that it is overly complicated, that is the diagram that the Diode Dynamics recommended I use for their lights.

What you described is exactly what I was hoping to do because I just want the lights to work off the AUX.

I feel better knowing I’m not the only one that thought it was overkill, I appreciate you confirming it!
