How should I modify the attached aftermarket fog lights wiring in order to connect it to aux switch? The harness comes with 3 pins/cables, while aux switch only has 1 cable.

The switch will have the following:
The relay is the black box in the wiring harness. Should have four (or potentially five) wires running to it.
Option B is to cut the entire relay/fuse/etc. out and power the lights from the Aux switch itself. Should be fine, just know what the amp draw is and pick the correct Aux line.
- Power to the switch
- Power from the switch to the relay
- Ground

You only need 2 wires. Power comes from the Aux switch wire , the other to ground. No need for that switch or relay pictured.
Beat me to it, great advice, and correct!

The highest aux switch rating is only 30A, so if that number is correct you may need to wire in that relay. Seems crazy that those 2 little lights are 40A
Do you have a link for the lights so I can look at the specs?

Okay nevermind. 50 watt is nothing. You should be fine using any aux switch you want without needing the additional relay.
