MG Car Repair: 1974 MG Midget Gauge Wiring, coolant temp, wire colors

Question
I am trying to put in aftermarket gauges into a MG dash.  Somebody had already taken it apart, and I'm attempting to put it back together.  The manual that the owner of the car had doesn't have correct wire colors.  I need to get the diagrams for the Tach, Coolant Temp Gauge, Fuel Gauge and switches for the dash panel.

Answer
Hi Bill

Every gauge has illumination (Red with a stripe, either white or green)

Every gauge needs an earth - plain black ring terminal attached to a holding stud.

Tacho has a green power line and a white/black signal line.  Signal line has a bullet connector.

Temp gauge - I think this is mechanical - no wires.

Fuel gauge has Light green/Green power and Green/Black signal.  Connect either way round.

Light Switch:  Brown power, red to sidelights, blue to headlights.

Will that do?  Ask if you need more.
