I’m trying to wire up a pair of early xj40 seats for my Mk 2. Does anyone know which wires provide the live and hot feeds? Do I need to relay all the switchgear?

 

I have the electrical guide for a 1993, hopefully that is close enough. Here is the drivers seat wiring.

 

Just be a little wary on the wiring diagrams.
Early XJ40s had the battery in the engine bay and somewhere about 1992 there were major changes to the electrical system and the battery was now in the boot (trunk).
I had a late model 1994 XJ40 and the early pre 1992 electrical wiring diagrams bore no resemblance to that car.

 

Thanks, I’ll hack at it using small value fuses I think.

 

I noticed the date on the switchpack was 1992, so I think the 93 guide is probably similar. A 92 would be better of course.

 

It may be worth joining the JEC and making contact with David Marks. He knows the XJ40 inside out.

 

Hmmmm JEC eh?

Sorry to hijack, but in all my searches I hadn't seen that one go by. I'll have to bookmark it. Thanks.
