    I mounted the controller under the dash just left of the steering column last night. I'll post some pics later this weekend And I'm making a panel that will go under the passenger side rear seat for the relays, sensor module and motor module. My idea is to keep all the electrical components inside the jeep. I should be able to start working on the wiring this next week, with the goal of installing the transfercase and being fully functional on the weekend of the 20th. Hoping for no Gear Ratio errors in Low or Low Loc. Reading the service manual, it could go either way. Best bet is I will need to shut off traction control, which makes the ARB rear locker and "manual" front ELSD more important.

    To mount the Transfercase Select Switch, a couple holes need to be drilled on the bottom of the Shifter storage area. And a hole provide for the Switch Plug to plug into the rear of the Switch.
    I think I can make a template for these holes.

    Here is the Transfercase Selector Switch mounted and plugged into the stock wiring harness. My XK had this wiring in place. But it needs to be modified to work with my controller.

    Here is the modified wiring, Pins 1, 2 & 3 cut and wired to run to my controller. Please note I have soldered and heat-shrink-ed all connections and sealed of cut ends of wiring harness that will not be used. I have run these wires along the stock wiring harness using tie-wraps. All changes under the console are complete.
    Next will be making up the panel to mount the two modules and relays that will power and control the Transfercase Motor, that will be going in under the passenger side rear seat.
    After that running the wires between the two areas, adding the key switch and testing the Transfercase before actually installing it. One step at a time.
