OK, I was trying to keep things simple but have managed to make things very confusing (as usual).
I don't have all pics as it was raining when i did it so have stolen some images from the net.
The reason i chose this camera as i know it to be compatable as NTSC with in-built controller and guidance lines (i'm sure others will work, maybe a camera for a scirocco or transporter van etc.)
To do an instal you only need 1 repair wire (double-ended) that can be cut in half.
This camera comes with:
Standard Yellow rca cable
A small loom to provide power including 2 loops of wire that can be cut if required for different functions).
The yellow RCA cable needs to be modified as there is nowhere to plug it in to the media unit, or an adaptor lead made. What i did was took 1 end and cut it off leaving the yellow core wire and the braided shield.
Attach the yellow core wire to 1 half of the repair wire and attached the braided shield to the other half of the repair wire so you now have 2 ends:
These pins need to be placed in the quadlock plug in the rear of the media unit (the blue plug needs to be un-clipped from the quadlock then unclipped to insert the pins)
yellow core wire (video source) pin 6 of the blue plug
Screen wire (earth) pin 12 of the blue plug
This wire with the power cable, will now need running down full leghth of the car to the camera.
to be contiued....
