Lift gate/hatch wiring question

Long story short, I have an 07 Yukon base package no frills no auto lift gate. I backed into a Jeep with a large bumper guard, so my hatch was toast. It still worked, opened and closed properly but was pretty smashed. Fast forward about 10 months I’m cruising thru Facebook marketplace and see a matching color hatch. Bought the door and mounted it up, this is when I realize it has an extra wiring harness. I figure the door came from a suburban with the auto lift gate. As of now the handle to open the hatch isn’t working. The rear wiper works so I know there is power to the door. But that is all I’m sure of. New door also has a back up camera which the original didn’t have. Hoping someone has some ideas of where I can start. Thanks in advance for any info.

By hatch, I assume you are referring to the entire assembly, not just the glass, correct?

If that is the case, can you open the glass with the button or is that not working either?

Either way, I might check the condition of the switch/buttons on the new assembly and see if they are bad.

Yes entire assembly, the whole door. The button for the glass release( external) is missing. I’m going to order that today. Are the 2 connected? If one doesn’t work
