2021 Ram 1500 Limited Multi Gate Removal Problems

[sivxmon]

I have a 2021 RAM 1500 Limited that’s after a rear end collision. The car originally had the 60/40 barn doors, but we opted for the classic drop-down hatch. We put the tailgate in, removed it in AlfaOBD, so the car doesn’t look for the module. Now the tricky part - how does the release handle work? The hatch releases with the key or from inside the car - not a problem. But the problem comes when it comes to opening it using the handle. Plugging the handle in and clicking it does nothing, checking the plug using a multimeter shows nothing - although I believe it should have something? Is it the harness somewhere? Does the configuration have another thing changed or is there anything else I can do or try?
Thank you everyone in advance!
