No voltage to red/blue wire r33 gts25t

[G2trop]

Trying to get my headlights to work but there is no voltage at any of the plugs. The car was dissasembled a while ago and i have been putting it back together. I did not touch the main body loom only the engine bays loom. I did some testing with a multimeter and there was no power at the headlight stalk connecter on red/blue and no power at the relay in the engine bay. I found a red/blue wire in the boot and that has 12v i followed the loom up under the dash and there is no voltage at the plug (seen in pic) if anyone has any ideas or a good way to trouble shoot i would appreciate it as i am shit at electrical.

Get the wiring diagram. Find the source of the power, go there and probe. Then move forward in the diagram until you don't find power any more.
