I am about to fit an ARB driving light wiring loom. Question is: äre 2016 150 headlights [high beam] negatively or positively wired? Which wire to pick up on rhs headlight high beam please?

Correct me if I am wrong here, but I believe that all vehicles are positive active and negative earth.
Some models are 'positive switched' and some models are 'negative switched'.

As a general rule yes. Somewhere deep in my head tells me some of the early landrovers were positive earth. To get a signal wire locate the high beam positive and earth wires at your headlight and power your relay coil in parallel (via a cabin switch). In that format it doesn't matter if it's positive or negative switched.

I remember my old '67 Vauxhall Viva was positively earthed.
It was a pain to fit a negatively earthed radio to. I had to insulate the radio body from the car.

Here is the quick answer: the black one. If you don't want to hack into the factory wiring, buy an HB3 extension cable (http://www.ebay.com.au/itm/2-X-CARCH...sAAOSw9N1VrdgF) and hack into that.
