Hey Ant
if you take a look thru previous messages you can find a buttload of
info. I think the connector you are refering to is connected to
the "AUX" switch to the right of the steering wheel on the dash. Your
Proton dealer should have a plug to convert it into something you can
use if you don't want to rewire it. its just a power source for the
back of the ute, im running an Ingel off mine.
