I’m sorry, I should have made those two separate topics.
There is a plug and play harness for the rear Baja designs lights that I added to the AEV bumper using the AEV mounting brackets. Those lights go on and off with the reverse lights; I have not wired a separate switch. The gen5diy harness just has them mimicking the reverse lights (which is nice, for instance when you unlock the truck with the fob, those lights go on). You do have to put the ends on the pigtail to power your rear Bajas, but that kit came with the plugs to do that.
The other harness is for the front OEM fog lights. That harness is also plug and play and allows for the following (and there are options, this is just what I chose in the harness I bought;
1. OEM fog lights come on every time I turn the headlights on (even on Auto mode) - so I never have to turn them on manually again
2. They stay on when the high beams are turned on (this required a wire to be connected to the + terminal on the battery)
3. I opted for an additional high beam tap wire out of the same harness, so when I eventually add a light bar or driving lights, I now have a dedicated tap that only goes on with the high beams, which is exactly what I want for those kind of lights.
Two totally separate harnesses, purchased separately from gen5DIY. OEM quality connectors, totally waterproof. They go inline between the factory wiring, so true plug and play.
Hopefully this clarifies some things.
