After putting my sj back together I can't work out where the wiring conects to, they come out by the fuse box (white/black live/earth) and 3 wires come out of the loom I think I can't remember with out looking but I believe there is a red, orange and white I am assuming white goes to white for the interior light and one is for hand brake and the other I don't know but my problem is I can't get 12 volts from the white one cheeked fuses but still no luck if it is defiantly the right wire then I can incestigate further but I didn't want to get to far in to find out it isn't the right wire anyway so and help appriciated

I believe they are on the same fuse as the stereo and the horn, so if they are working you should have power there somewhere

White is for the interior light (does also feed other things)
Orange is the hand brake switch
Red could be a number of things.

There's a thread at the top of the electrical section with loads of wiring diagrams

Does the white one go via the door sensors?
I think mine had working door sensors when I got it but I could be mistaked I haven't had a working interior light for several years haha
