fusebox wiring

basically i changed my fusebox and fixed my dashloom recently now i cannot remember for the life of me how the brake fluid/handbrake light on the dash is wired up    any pictures help would be gratefully recieved

iirc theres a black wire from fusebox to the light, the -ve side runs to a 1 pin plug near the fusebozx and from there to the switch. see the fusebox faq anyway might help
