Oh, fer feck sake. I though there were rules about posting links to other sites. I don't know for sure cos I didn't read them, but then 300tdistu blasts straight in there with a link.

The ones I was talking about are here
pdf Land Rover Manuals | Landroverweb.com
Also google for "defender electrical schemes" and "defender electrical library". for electrical stuff.
Apologies to the mods if I've broken any rules
