Good deal Qjoh5510 I hope it all works out. I’m like you, I will never cut a factory wire. I’ll always find the correct connector and terminals to either build adapters or extensions to suit my mods.
Good man, the correct way to go for sure:)

Does anyone know what wiring diagram shows the O2 sensor wires? I'm asking, because in the process of doing a frame swap, the drivers side O2 sensor wires pulled out of the wiring harness plug and unfortunately, the colors are different than the passenger side.

I just looked through all the wiring diags I have downloaded here and dont see anything for the O2 sensors sadly. For my own morbid curiosity why are you having to swap frames?

Thanks for checking. I found what I needed here:

http://connectors.dcctools.com/details.htm?id=274235

As for the frame swap, I bought a rear ended JL from an insurance auction and learned afterwards that in order to pass the MA State Police salvage inspection, you have to replace everything that the insurance report says needs replacing. When I bought the Jeep, I thought I was going to be able to have a local auto body shop straighten the frame on a frame rack, like VTuned does, but no such luck. I didn't save any money, but it was a fun project. I worked on with my 12 year old son and it took us about 9 months to do the frame swap. We passed the salvage inspection about a month ago and the Jeep has been lots of fun driving around.

WOW, ambitious project! Sounds like a winner & I'm sure your son learned a lot (maybe you did as well) :) Glad you found what you were looking for & I bookmarked the site myself for reference, Thanks!

On my Willys 2021 3.0L, I see two ground connections to the frame behind the front passenger wheel well:

Going by OP's diagram, I am guessing they may be G906A and G906B? If not, what could they be?

The second one at the bottom as below, does not have the sleeve and the silvery solder like end is exposed. Is it the way it is supposed to be and not cause problems down the road?

Excellent pics. Yes I think these connections could become a future nightmare. It wouldn’t be a bad idea to either cover these connections with either a good quality undercoat or use liquid electrical tape. Especially so if you live in a state where streets are salted in the winter, if you’re driving your rig on the beach or park on any grassy surface, rust will form on those grounds.

'23 Jeep Wrangler 392
Trying to replace the '23 headlight switch with the 21'-22' headlight switch that allows for the two dimmers, i.e. dash and footwell (ambient) lighting. Plug is the same. The 21'-22' headlight switch, part number 6822928842AC. It works all except the secondary dimmer. The wires on the harness match the pins in the two wheel switch connector. There is an orange wire with a yellow chaser that connects at a pin that is not there on the single wheel switch (23').
Would welcome any thoughts or suggestions.

I tried the same. Pretty sure it's a change in the BCM.
