hi, i have the 150 as well, what colour wires did you mod to get the rear camera to work, but i think mine will be a little different as i have the kakado model.
but i have done:
hid spotties, already has hid the rest from the factory.
front bar,
2 inch lift in rear, its just a computer mod as they have airbags and no springs in the rear. about to do the front.
uhf under the seat, but mic in almost the position as yours.
dual batter system.
compressor under bonnet.
it is a petrol model.
towbar
roof racks
mickey thompson tyres.
thats about it for now. it has everything else i need like factory fridge/subs/power points/diff locks 4 cameras, radar anti collision, kdss, adjustable shocks and so on.
