Chasing info on the rear accessory panels in the GU's if possible, the area where you can pick up the 12v multi plug gang plates.

Looking at what other's have set up for ideas on putting my own in. Also chasing pics of what is set up behind there or descriptions of wiring, as per my intro post / pic, trying to figure out what this cable set was used for? There is a red, blue, yellow, white and i forget the other colour possibly black but can confirm that when i get home from work.

Any info appreciated as I am a complete patrol nOOb.
