Super S cluster swap problem

[Johnthorn]

I’ve just swapped the standard instrument cluster on my 96 1.3 GX for a European spec rev counter spec cluster.

I’ve managed to swap the Speedo, complete with original odo and MPH scale, Rev counter works (albeit intermittently but superglue to the flexible circuit board should cure this)

Engine temp works fine.

Problem is the fuel gauge appears not to work!...any thoughts folks?...
