Mate, check the fuse.
If you didnt remove the fuse before you started messing with the wires, its possable you may have shorted it, causeing the fuse to blow.

I do this all the time.
Have a bag of 50 fuses from work in the back.
Just for occations like this


Cant help you with the colours though mate, Ive never owned a Polo before, so I'll leave it for someone in the know

Good luck with it bud.

Yeah cheers for that.... Silly me didn’t think of changing the fuse
Still want to know what this wire is for people so any help would be great
Thanks again…

Is it brown, with a red stripe?

I recon you are correct with your thinking and it is +12 Volt Ignition Wire
