Default WH Driving Lights

Okay!

To wire in your driving light circuit its the same as any Aussie built Holden or Ford, switched positive.

I tapped into the WHITE wire on the drivers side headlamp as the trigger.

YES you will read a voltage of around 10/11V on the white wire when it is not on high beam, this is (albeit an educated assumption) a sense voltage that the computer uses to detect a blown globe or short.
If you connect up an LED driving light directly to this voltage it will glow but not light up, it's not able to supply enough current.

How I did it.
1- Tap into the WHITE wire on the drivers side headlight and run the wire into the cabin to the driving light isolation switch, some people fuse this but I didn't. I know, I'm a rebel

2- From the switch run a wire to pin 86 on the relay.

3- Ground pin 85 on the relay

4- From the battery run a wire to pin 30 on the relay (with an in line fuse ).

5- Connect the Driving light/lights to pin 87 in the relay

By the way I will change the title of this thread to WH instead of WK as there are subtle differences between the RHD and LHD versions that can lead you astray.
