HELP please…full interior swap tradesman to Laramie…seatbelt wiring

[Lure]

Ok I did a full interior swap complete interior harness and everything…except curtain airbags and camera behind the mirror it was a 2019 truck
My truck is a ram 5500 2021 tradesman…now I can’t get the truck to start or figure out the 4 digit radio code. The truck will run through startup and says needs ( abs, airbag, transmission service ) I ran the alpha OBD to seat up the heated seats and turn off the parking sensors etc. that I don’t currently have. But it’s gots some problems…it has fault codes
U0200 pass door module
U0121 lost comm with abs module
U0101 lost comm Tcm
U0100 lost comm ecu/pcm
U1514 engine controller secret code

Please help me figure this out…

Also I had vsim on my old dash harness but didn’t install it with the new dash…could that be part of the problem?

The modules that show no com shouldn't be to hard to figure out, check for power/ground and network activity at the module.
Which modules did you bring over from the 2019 truck?

I just swapped the dash and harness fully assembled I didn’t even think about modules…I did notice the dash plug is missing one wire from the old harness and has one extra but I’m not sure what they’re for.

The new harness does not have a vsim module though

The VSIM shouldn't matter if its there or not. You may have to compare connector pinouts of both trucks to figure out the issue, Ram likely made some minor wiring changes between those years

Any idea where I can download the pinouts?

This is a good free source for connector pin outs

It looks like the connector you are working with is XY401A but double check the wire colors, Ram may use this connector in more than one place

These diagrams are a lifesaver! Thank you

I extracted the vsim harness as well as and double checked the new harness.
It’s populated as needed.

I did originally install it with the new vehicle tow brake module, as well as the gateway park assist module. I’m going to swap those and reinstall everything. I also swapped my original aux switch with pto button on the center stack…Hopefully I get a different outcome.

Update I got the truck running I just have a tone of weird codes but I’m going to work through some and get to a list of codes I can’t resolve.

Slowly working through things and everything works now except my airbag light is on…I didn’t grab the 3 stage seatbelts from the donor truck…and my 5500 doesn’t have any wire connection at all on the retractors…do I have to upgrade the seatbelts or can this be bypassed somehow?
