Finally the easter weekend has given me time to have a play with the big girl,
Firstly changed the spark plugs, I don't like leaving them 75k seems to long. Bit of a pain but got there in the end.
Then had a look at why the Cubby fridge was not working
Removed neg from battery
Removed the stereo surround
then gear knob
removed the ride and handling optimisation switch
then the upper floor console
remove the cubby lid, then the two torx screws on the front side of the fridge, sharp yank, and voila the cool box pops out.
I then plugged the ride and handling optimisation switch back in and re-connected the battery.
Then checked that i had permanent 12volt to the cool box
switch on the cool box and short across the diode and resistor as on the pic below. sorry poor pic as only thought to take pic when i was putting back together.

anyone have a electronic scheme of this circuit???

I want to replicate it to get mine running in my D4 as the D4 are ign switched and I want to get the cool box running on aux batt to preserve primary one for starting purposes only but I don't want to get the aux flat.

Thanks in advance
