2017 Nissan NV3500 HD SL, Radio Wiring

Some crack head cut out my head unit (Ig they were in too big of a hurry to just unplug the damn thing) and I have been looking for a wiring diagram to fix this mess. It wouldn’t be too different from older years, would it? I’ve found a few (2013) but they seem to say different wires are for different things. Not only that, but a lot of these wires are the same color to one another with no stripes or any indicating features to distinguish them from one another. Im not sure what other information to give. It was the stock touchscreen double din with navigation, xm, etc. The whole vehicle is oem. I found a cheap replacement unit to replace it, but am currently stuck at figuring out which wire goes where. Have a loooong road-trip ahead… tia
