There have been many questions, rumors, and opinions on whether or not the Selec-Trac transfer case could be swapped into a part-time configured Jeep. I set out to answer the question.
Initially, I thought I could swap the transmission wiring harness, the Transfer case control module and reprogram the BCU. But after many hours of wiring harness comparison, and shop manual review, I have come to find the dash and body wiring harnesses do not have the leads for the transfer case stepper motor control. The harnesses aren't that expensive and I have contemplated swapping them but have since decided against the effort. Then I thought about building an 8 wire loom to bridge the gap but decided against that too.
My Gladiator is an early 2020 build, perhaps the later builds have the provisions built-in but I doubt it.
For those who want the Selec-Trac, buy a Gladiator with it!
I am happy to share more details of my findings for those who are curious or want to pick up where I left off.
