My dealer just left the settings for 33" tires as their was no option for the 35s.
does this new bypass harness negate the need to visit the dealer at all?
complete plug and play at home and no dealer visit to "lock in" and finalize the code?
i anticipate installing the bypass harness, plug in procal, remove both, and never plug it in again?
I guess it's ProCal or nothing, then.
I'm not sure if it still requires the dealer to lock in the code for the TPMS adjustments.
I didn’t read the 2018 instructions, but I’d wager you still need the dealer trip. I ordered one for my 2015 by phone last week and the guy I spoke with said the only thing new about the 2018 model is the harness to bypass Ram’s security feature, same old Procal module.

Got the bypass wiring installed and set the tire size this morning. Toyo MT 35x12.5 measured out exactly 34" in front. Speedometer is now accurate to within about 1/2 MPH, verified by GPS app on my phone.
I had to use the photo in the instructions of where the wires plug into the back of the ODBII since even though they say the plug slots are numbered, I couldn't find them/see them even with strong reader glasses on.
[Removed comment about connector plug – issue solved]
Interesting that the RAM ProCal can never be unpaired with the vehicle unlike the one I had for my Wrangler.
One thing is for sure – I got way too used to driving this thing with the speedometer being off – feels like I'm going so slow when I drive the speed limit now.
Did you check to see if the ProCal worked in thr OBD II without issues? I just installed mine and used the provided OBD connector cable and had no issues.
Did you check to make sure the wires in ports 1 and 9 were seated properly before you put the locks back in? It's possible those two are causing the issue unless the ProCal works in the port without the connector.

I figured it out – user error. I wasn't pushing the connector cable far enough into the ODBII so that it locked in place. Works perfectly now.
TPMS settings updated by visiting dealer. I had a copy of the page from the ProCal manual with the appropriate instructions highlighted, which really helped. ProCal is done.
Next up, figuring out where/how to mount the full size spare. I was going to go with the Wilco tailgate mount, but I don't want to relocate the backup camera or worry about the parking sensors. A bed-mount of some kind looks like the best option at this point.
this is a beautiful set up! Love it!
