2021 RSE Idea - Anyone good w/wiring?

[sodacitydenali]

The idea of having HDMI/USB cables hanging out of the center console in the back bothers me, on a $80k+ vehicle. I feel like the HDMI and USB inputs should be tucked away, both for aesthetics, and also to keep 5 year olds from kicking them when they're walking by or hauling their backpacks in and out of the vehicle.

So, my thought is:

If the wiring harness can be spliced/expanded I could relocate the HDMI/USB module inside the center console compartment, under the arm rest, and in its place put a simple USB charging module (which would come standard on a model w/o RSE).

It would take a little bit of drilling, to break through the wall on the center console compartment, but I could get a 3D printed enclosure to hold the module, and attach it to the console interior, to give it a clean look and hide the wiring adapters.

Problem is, I don't have the knowledge/expertise/experience to splice the wiring harness (or create splitters) in order to connect both modules.

I've done a little hunting to find some diagrams and pictures of the back side of the module. GMC is using a proprietary enclosure and connector it seems.

I've attached pictures/diagrams I've found...would love to hear others owners thoughts on this. Especially if you have the expertise required to splice into the harness.

I saw that Gen5DIY did something similar for a power adapter for a radar detector, and they also have the auto-stop eliminator..which makes me think this is actually a possible avenue.

Splicing USB may work for power, for signal, be careful.
HDMI is worse...HD bandwidth requirements are such that those cables are somewhat sensitive...
Net, be careful w/ the splicing...

You may be better off just removing the HDMI module from the mounting, and tuck it inside the console, and then just make a plastic cover for the spot where it goes.

I was looking at the module pictured above, and comparing it to the usb-only module.

The USB only module only has 1 port for connection - which implies to me that (on that module) it's only for power.

The Above-pictured module has 3 ports, which to me means: 1 is for USB power, 1 is for USD Data, and 1 is for HDMI signal. If that's true, they you only need to splice the power port, and re-route the HDMI/USB data plugs to the second module. Which makes it sound like the entire job just got significantly easier.

Problem is, I don't have a donor harness to really mess around/test with. So, unless I can get an actually wiring schematic (probably) it's all just a fancy thought exercise :|
