So today I sorted the electrics, made the error of ASSUMING, something belonged somewhere. So I blindly connected the earth to the hotwire, essentially putting a wire across the batterypoles.
After I realised my brainfart I started cleaning up the harness, so now I have a fully functioning harness again.
The brakelight is slow to come on, I'm told this is the nature of 6v electrics, does this hold any truth? I don't see why.
