hi, a tiger eh, I've a mate with one of those, sticks to the road like glue, a bit windy at speed though
Best thing would be to get hold of a haynes manual for the Sierra, in there are all the pin and wiring diagrams for the switches. If you don't have one, I'm sure someone here or on the tiger forum will be able to lend out or scan the appropriate pictures. Where are you, there are Sierra manuals in most cobra builders garages. what about your supplier, I expect they could help too?
cheers
