Does anyone know what the white wire with orange tracer on it is for? coming from the fuseboard and through the bulkhead Haynes is a joke and I cant find a decent diagram online can anyone help. Sorry forgot to say this is on a defender 110 1994 mreg
cheers lee

orange with white i think is air con
no much use if you don,t have it

Use a bit of logic and trace it out

Mines a 200tdi and that's got a white orange trace going to the ignition switch. I think I've read somewhere when I was looking up the wiring its for accessories.

LOL you have a steep learning hill to climb, Last week I was trying to wire a fog light on a 110, red with grey stipe and black came off the switch.
BUT it was a orange with white stripe wire that was live at the bulb.

I did trace it out through the bulkhead and along the loom and then i found the rnd of the wire not connected to owt? but wires were slightly melted hence my concern clever clogs

Yep found white with orange tracer from ignition to fusebox then there was a white with orange tracer coming out and going through the bulk head and wasnt connected to anything, but at the other side of fuse box i had a white and orange going to white and orange thinner wire than the one on ignition?reason fory concern is part of the wire coming out of the fuse box was melted?

does that help?

cheers thats a big help mate.

So ones for air con ones for a radio cass and not sure on third if there is a third? anyone else come accross these wires?

Using a guide to standard wiring colours (Lucas?) can help e.g. http://www.mgexp.com/article/lucas-colours.html although there is no guarantee it will be 100% correct, especially if a previous owner has done a bit of DIY electrics

Has anyone else had any dealings with white wire with orange tracer on a landrover defender? says on wiring diagram 1 wire is for air con if fitted one is for radio cassette but not sure about 3rd wire.
