Simplify JK wiring to bare minimum

so id like to start the process of turning my JK into a buggy-ish trail rig since its no longer on the road.

aside from hard parts like the drive train, id like to figure out how to simplify the wiring so it has the bare minimum to make the engine run.

i dont plan on doing a V8 anytime soon so the 3.8 will be sticking around so this will be what i have to work with. is there any sort of stand alone market for these engines? if not, what would be the best way to go about it?

There is no stand alone that has a pre-made harness for the 3.8. You would have to build one yourself which I am guessing would be a somewhat challenging task since no one has done it before.

You would need to keep the Jeep PCM, TIPM, Cluster, Ignition switch, WCM wireless control module to allow it to function without a ton of work.

I would just keep the stock harness intact and all components in place unless your ready to open a huge can of worms.

Just throwing this out there. We are working on a standalone harness that will allow you to drop in a complete 3.6 powertrain into a early JK or anything for that matter. This would be a better route than trying to make a 3.8 standalone. And the 3.6 pullout powertrains are really cheap right now and make way better power compared to a 3.8.

RPM Extreme that sounds like a winner. Would this work with the updated 3.6 in the JL?

Im not sure about the JL 3.6 yet. Im not convinced its any better than the JK 3.6. They added a bunch of emissions stuff to the JL 3.6 and made it overly complicated IMO. I was told that this was to achieve the higher emission certification. LEV II+ I believe... don't quote me on this

Right now the JK 3.6 pullouts are stupid cheap and with proper tuning will make great power compared to the 3.8

Start the jeep.
Cut one wire at a time till it shuts off.
Butt connect that wire back and keep going.

Really tho, there should be a pin out online somewhere and start there. I will be trimming wires shortly but it's pretty straight forward
