Hi, I'm looking to make a small modification to the "spot lights" that were on my escudo when I bought it but need to know the colours used in the standard wiring loom first. Basically my intention is to swap the wire that powers the relay from the parking lights to the high beam so they are "automatic" I'm adding proper lights but thought I may as well keep these too.
Thanks for your help!

Also does anyone know what the little white capped off plug beside the relay holder does? It's a factory fitted plug that Is not connected to anything.
