Re: Ute wiring for centre brake light
Sorry mate, seems I was wrong - the two wires in the connector I told you were brake light (as you found - should be dark green with red stripe) and reverse light (should be red with black stripe).
I haven't found a seperate connector for work/cargo light yet, but I'll let you know if I do. However, I assume you just need 12v power for this as you'd have a switch installed with the light - in this case you can take 12v power from the trailer plug connector.
There is a trailer plug connector hidden up under the back of the ute - up under the rear bar kinda - behind the spare wheel - it's a grey multi-plug connector which if you have a towbar installed, your actual/external trailer plug connector just plugs into this connector, else it'll be unplugged. The pink wire (or it could be yellow with a black stripe - there should only be one or the other - I just can't tell where they join on this schematic :) on this connector is 12v - it seems to go back to a 30A fuse in the fusebox and is constantly live (direct from battery).
NB. This info is all from AUII workshop manual but I'm guessing it should still apply.
