My Truck 2017 1500 Big Horn

I installed a used CHMSL with camera from a 2500 Ram. I have had the lights working for some time now but I just got around to wiring up with harness I made based off the information I could gather. I followed MKS Performance & Offroad video on YouTube knowing his was a 2500. I put together a spreadsheet to help me keep everything straight. 1660562739314.png

Everything has gown as planned until I tried to find Lin Bus CBC3, and Run Relay Control at i440 behind the drives C-pillar. They don't seem to be wired in on the 1500, or at least mine. I have everything complete I just need to find where to connect to these two wires. If you know where to find these on the 1500 please let me know. If you have a wiring diagram for my truck that would also be helpful. Thanks,

This might be the 3rd brake light that has 2 cameras
1 is a Cargo Cam, the other is a video camera

but it should show you how to run the wiring

it covers the CBC3

Thank you, that is the YouTube video I used to make the spreadsheet. It is also what it followed on my install. The video was very informative but the issue is on my 1500 the two wires are not at the plug behind the C pillar. I have already landed the two wires on the tops side of the plug just as shown in the video as I prewired my harness. But CBC3 and Run Relay are not their.

If anyone has a wiring diagram from my truck that would be very helpful. I thought I remember several members did this install on their 1500s. Any insight from someone who has completed this install would be great. I am so close to having this project finished up.

Thank you for the diagram. I have some new pins on order to connect it to the original intended location. It's odd looking at the 2013 diagram of i440 it shows they should be thier on all trims. They mist have dropped them at some point. I was not able to find the i440 diagram for the 2017 1500 to confirm.
