Hi there.
Just brought an XJS off Trademe and need some wiring diagrams for it. Its had a rat under the dash and engine bay eating a bit of the wiring. Especially need some info on the Lucas ignition amplifier unit. Its had the wires chewed off it!
Thanks in advance.

Thanks Clarke

 

If you PM your email I can send you the S57 wiring guide for early 80s vintage XJS. It might be helpful for certain things that didn't change much over the yeas but won't include anything pertaining to the 70s vintage Lucas ignition.

Cheers
DD
