I've checked the wires that feed the headlights but it is not as simple as 'low beam-one wire live, high beam-other wire live, feed relay'. All wires seem to be live when the lights are in different positions. There is also a wire that is live on high beam, not on low beam then live again on park and lights off. I remember having (and solving) this problem on another vehicle some time ago but can't remember what the solution was. Can anyone here enlighten me before I pay a visit to the local auto sparky for advice! Cheers.

To sum up, all I want to do is feed the spot light relay on high beam. Cheers.

By your description I would say It's a negative switching system you need two wires to feed the relay from high beam the negative and the feed wire if you are confused pull all the plugs off the lights and test with lights unplugged that way you wont get confused by the back feed through the bulbs. The two wires will go to 85 and 86 on the relay respectivley.

Thanks for the reply. I did pull the plug off and test, and was still confused. Can you explain further what I need to look for and connect. How will I tell if it's a negative!

unplug left and right lights test for power with lights on there will only be one power supply with lights disconected. Connect the power to 86 of the relay now put ya test clip on positive of battery flick high beam on only one wire wll light up the test light, tap in and connect to 85 of relay connect 30 to power and 87 to spotlights ground the other side of the spotlights
