Wondering if the electrical diagrams I have, years 90-91, are the same and can be used when working on an 89 XJS. My interior lighting has failed completely and I was hoping the information I have can be used to help solve the issue. I've checked the fuse and it is good. Still need to see where the voltage stops. I'm attaching the diagram I have. Thanks in advance for any and all help.

 

I have the '89 diagrams. PM me with your email and I'll send 'em.

The '89 circuit looks different to me.

The interior light circuit has always been a brain melter for me.

Cheers
