The media rack has been annoying me for some time and was in need of a tidy up after previous owner had a after market dvd changer fitted and wired in along with monitors in the head rests and my retrofit of the reverse camera.
My routing of wires wasn't the best first time round and I spent quite some time today taking the rack in and out whilst rerouting harness and cloth taping them in.
I also had the mystery item in there that i wanted to remove if it wasn't doing anything too.
I assume the mystery item was a tracker as it wasn't connected to anything other than power and appears to have an antenna or two.
Its out and gone now happy days.
The rear screen installers did a good job but then cut corners on the Aux input wires.
I found today whilst fitting an output harness to the tuner that the input they had wired in from the DVD changer was tinned wires pushed into the plug in the hope that they connected with the pins in the tv tuner
Surprisingly they never failed but thats been binned now.
So I now have torn out all the unnecessary wiring and fitted the Output from the TV tuner to feed the Rear screen inputs and taped and tidied it up to my satisfaction.
People that are looking for ways of getting power in the boot should perhaps consider what the installers had previously done which works quite well and thats add a separate fuse panel with relay like in the pictures.
It allows one to add switched live and permanent live feeds to whatever you need.
The relay is switched by the black/yellow wire from the parking module pin 1 IIRC, and fed from the supply on the other fuse box next too it.
All back and and working first time so happy days.
