Hi all,

Car is on for MOT, has failed on the illumination of speedo/instruments.

Has anyone got a wiring diagram for the back of the cluster and headlight switch?

Thanks all in desperation! Car cant get an MOT without this problem fixing.

Have you checked the light bulbs at the back of the instrument cluster? (They usually go out gradually, one by one.) Any other issues besides the lack of illumination? Here's a link to 740 manuals (there's a wiring diagram there too). Hope that's helpful.
