Hi, can someone please tell me which pins are the power and ground for the MKII, MKIII, MKIV navigation computers. Each harness (blue/purple) has 18 pins. I want to be able to power on my MKIII using a 12v battery, to test and see if it will accept a cd.
Greatly Appreciated!

The blue plug is all you need (the purple one is for the wheel sensors). It's the same as the blue one on the TV module :

You may require some iBus traffic to wake it up, I'm not sure.

I believe you are correct.

OK, excellent! Pins 1 & 10 are the ones! Pin 1 = Power, Pin 10 = Ground. When 1 &2 are powered with 12V, and 10 & 11 are Grounded, it will not work on a test bench.

Thanks for your help!:cheers:
