    This thread is how I added auxillary switches to my 2016 RAM 2500 with a 6.4. My truck did not have provisions for the auxiliary switches from the factory and the parts folks at my dealer said it was impossible to add the switches after the fact. After a lot of research I began my quest to prove them wrong. The switch in my truck had traction control, tow/haul, rear park assist buttons on top and a blank panel on the bottom?

    The switch I needed with the auxiliary switches on the bottom row was PN 68241343AA-001

    Both switches use a single connector and i was able to incorporate my harness into the existing connector by slicing into the appropriate wires.

    I found a wiring diagram on Ram Builder for the 6.4 and it* helped with the design and building my harness. In the factory connector I connected to the following wires.

    Aux1 - pin 3 br/or
    Aux2 - pin 2 br/vt
    Aux3 - pin 11 br/wt
    Aux4 - pin 10 br/gy
    Aux5 - pin 12 tn/br

    Since I introduced my own harness from the switch to my relays, I did not have to add the sales code for the switch. The switch itself applies a ground to the coil side of the relay when applied. Auxiliary #1 & #2 will function with the key off, 3-5 require the key to be on to function.

    Here is a couple pictures of how I ran the harness through the firewall by going through the clutch delete plate. It is plastic and easy to drill.

    Below are pics of the relay/fuse block I installed to support my switches.

    Purchased from Amazon -Auto fuse box 6* relay holder.

    Currently I* am only running Aux1 and Aux2 on the switch for my lightbar and for the led lighting I am about to install in my bed. (The other buttons are wire to the relay bank waiting on another project.)
    The mounting bracket I fashioned from a piece of aluminum angle I had laying around.

    Hope this helps you install your switches.

    Nice write up. Looks very clean and neat. I have this project on my wishlist.
    Are any of the AUX switches latching or MOM only?

    The p/n is wrong. It should be 68241343AA.
