Thanks for the replies.
All the wiring was in a right old mess when I got the Land Rover, not many of the light etc worked and there was a load of extra wiring that i removed.
Since I've started working on it I have disconnected the wiring to take the bulkhead off for spraying, so not fully sure where everything went, but would really like to get everything back to standard.. The only wire left is a one to the reversing light, so maybe it is manual switch for that..
I will have a play again at the week end.
Thanks
