which wire

im looking for the wire that comes out the back of the fuse box which i connected to the fuel pump under the tank (fuse5) but i have no idea what colour it is can anyone help?
thanks

You don't say which model…but likely to be black/green to a connector behind the instrument panel and then red/green to the pump.
Cheers, J.
