I've been trying to find wiring diagrams for my 9n as my fuel gauge is still not working and I've narrowed it down to the ground wire but not sure where this is.... Can anyone point me in the right direction for one? I've looked around this site but can't seem to find anything.

The ground side of the sender goes back to the speedo on plug 32a pin 32 (Green plug) (sensor ground) the speedo main ground is on the Black 8 pin connector pin 8 and that connects to ground at two places, 1 on top end of steering column & 2 under centre console near gear lever

I've done some work under the centre console a couple weeks ago so might be that I've disconnected or damaged that wire. I'll check after work. The one on the steering column is fine though.
