BL Sasquatch Aux 4 wire impossible to find

Today at 6:09 am

Has anyone actually found the Aux 4 switch lead wire? I have extended and wired Aux 1-3 into the engine bay for easy access, but for the life of me, I cannot find the last one. The diagram in the manual and Melissa’s guide is hard to figure out exactly where it’s at. Some have mentioned it’s behind the passenger wheel well. I opened it up and didn’t find it there.

Why did they make it impossible? 😭

Any insight or photos would be very appreciated.
