A/C magnetic valve wiring colour codes

[JACOBnzl]

After the positive wire please. Wires are yellow/red or yellow/blue on the magnetic valve that controls flow on the hard line on a RHD it's on the left side next to the radio antenna in the engine bay. Trucks a 92 but has a 95ish engine loom in it which doesn't have the plug for it.

I also can't find a Ewd or A/C diagram that has it

Thanks for any help
