2019 2500 Adding Lane Assist

[wbama387]

Hey guys. I am starting a thread for adding lane assist on a 2019 as it will require a custom harness. I am wanting to do this so I can get a comm.ai for those long trips. I have purchased a used torque overlay but need a little support from those that have access to electrical drawings for a 2020+ that has a torque overlay. I am pretty sure the yellow/red wire is power for the motor and the black is going to be ground. Can someone help me out with the other connector? My guess is one wire is CAN high while the other is CAN low but not sure about the third and which wire is which. Thanks!

I have finally tackled this project due to having to tackle the Hamilton kit as it was easier with the front end off. The components required.
1. UC5 upgrade with lane assist button on screen
1. Torque overlay - 68507900AB
2. Intermediate steering shaft as this one is shorter - 68427394AA
3. Harness - 68485757AA
4. Custom harness to plug into harness above

So I have the system mostly functional. The torque overlay is working so I know it is on the CAN Bus. The lane assist part is still not functional. I do not get the light on the dash and the button on the radio is not doing anything. I adjusted these settings.

VehConfig 7: Lane Departure Warning Present- YES

CustSetMenu 1: Lane Departure Torque CSM Present- YES

CustSetMenu 1: Lane Departure Warning CSM Present- YES

P/T Chassis Net: EPS Electric Power Steering- ENABLED

Anyone have any ideas why lane assist would still not be working? I saw that maybe the DASM I have part number 56029825AG may not be compatable with lane assist. Can anyone confirm this? Also, if it is the wrong DASM shouldn’t I still get the light on the dash for lane assist since I turned the feature on in the BCM it would just have a an error?

@Jimmy07 any thoughts on what might be going on here or what I might be missing? Thanks.
