My body shop guy ran into this…. Anyone got any idea why the harnesses between the original tailgate and the new one look so vastly different? It’s not just a yellow wire…

I THINK I need the schematic (and pinout / wire purposes) for MOPAR 68381399AC

Alright boys and girls. My truck got rear ended out on the interstate a month ago. 28,500 worth of damage. Still not totaled. My body shop guy came up with an MFT. We’re working the retrofit. Does anyone have access to the schematics for the tailgate wiring harnesses for the MFT and...

I can oulk the STL file and host it if you want. I like your idea for the simplicity…. Mine had a specific purpose, as I was planning the install from start to finish

i've run into this on my '20. I think the issue is the body panel under the headlights. Your bumper sits ~2" higher than a Laramie or Longhorn type Ram. If you mount the bumpers / bars you're looking at on the Rebel, they'll appear to sit 2" lower (really 1.75" from what i've read), leaving...

yeah, sorry, not thingverse... my mistake. check the tinkercad link i posted.

yes, i 3D printed it. Sorry for the delay - I don't get updates when someone responds all the time. The part is up on thingverse (update - it's on tinkercad, see link below) - it's a bit tight, but it seems to work well. The hard part for a lot of people will be getting the breakers, but if...

I'll see what i can find. would those be "normal" OBD2 codes, or do i need something more "invasive" like Alpha? I might contact the guy I bought this form and see if i can't swap it for the non-air suspension, but WITH PTO. PTO would never work, but that would be OK, too. I also wonder if...

OK. Removed the tazer - no dice. Is there maybe an enable line (ground or high) to cause the vehicle to talk to the "soft keys") (as compared to the piano keys)? It doesn't look like it, based o the pinout Jimmy provided, but the truck also backlights the buttons, which looks to be...

Yes, plugging the originals back in results in things working. This one DOES have the "extra" button (trailer height adj?) that my truck doesnt support... One thing i need to try is disabling the tazer aux switch settings and possibly removing the tazer....

Jimmy - might need your help. Or I might need someone with AlphaOBD in Iowa. Plugged the new module in. Backlights worked. Truck knew there was a problem with parking sensors when I unplugged it. Buttons did NOT work (park sense, Tow/Haul, Traction). Aux Buttons did nothing. I did notice...

Thanks for the advice!! I may put a drop of glue and some black paint on the "unuseable" button, since it won't have any function, and can't be repurposed. we'll see. I will try and document as I go on this one. Seems like there's been a lot of interest, but noone's taken it to the end...

This is the panel I ordered. I suspect the "ALT Trailer Height" button will either throw a code, or just not do anything, since I don't have that option. If it causes issues, cutting traces on the PCB is easy enough. What OBD interface do you use? I see a bunch that Alpha says do work...

AV8OR- We're a heck of a lot closer than we were.... or at least I am. Jimmy seems to have a wealth of information we haven't had before. If we can get the switches ACTIVATED (i.e., they light up when you push a button, and they send voltages to the pins he called out above), then we...

...and using an arduino to look for some logic signal and then respond appropriately to drive a relay - well, that's a lot easier to program than it will be to use the logic analyzer or scope to see what all the different wires are doing at any given time. hopefully there's a pin assigned to...

so, i might need to get AlphaOBD. luckily, i still have a balance on the giftcard i got. I had to buy 68376641 which also comes with trailer levelling. I don't have air suspension, so i suspect that switch won't do anything. the other option was 68376647 which has the right vehicle...

a bit late... I have the Tazer, have enabled "AUX SWITCHES" in the menu, and no "new" menus have shown up on the radio. I don't have the switch bank, though. I'm looking to buy one (moparparts is sold out), and then experiment a little. If the original functions all work, then it might be...

Here's a model number decoder for the switch panels. 68376640 is the one shown in the FCA docs (traction/tow-haul/front and rear parking and 6 aux switchs)

Given the 4th Gen setup and switch configuration, their response is actually interesting (I read it earlier, and just re-read it). Might have to watch the u-wrench-it type places for a rig with that panel.
