Maybe others with 4xe can chime in with their experiences.
Not a 4xe owner but about the sleep wake-up function. In the 2022 ICE wrangler, if it has OEM LED tail lights an additional wire runs to the ecm that will wake up the jeep anytime a brake light is switched on which then tries to self check all kinds of stuff. And throws weird errors.
This is not seen in non OEM LED tail lights.
I used the cooltech.com https://www.cooltechllc.com/towing-h...light-fix.html
Even though it is described as being for battery drain it may stop errors due to tow wiring.
Its a simple air gap double pole switch that works for me.
