What type of speedo is it and what colour wires do you have in the dash or is there none at all?

My mini is a 79 centre clock which had no rev counter or loom for one, this it is a second hand part that i bought as is with no wires.

Looks like a smiths rev counter

I take it the blue trigger connects to the ignition 12 volt supply coming from the ignition switch?

[Noah]

I don't know, I would've though red to ignition switch black to ground and Blue trigger to the engine somewhere?

Any one help?

Noah is correct, and the trigger goes to the white/black on the distributor side of the coil. You can pick up the positive supply from any plain green wire, not light green (ignition controlled and fused) and negative goes to ground, any black wire behind the dash will do.

Thank you both

Just to be sure is it + or - on the coil for the trigger as the wiring may not be origanal on this car

Assuming it is a negative earth car, it is the coil negative terminal, which as I said should have the white/black wire on it, if the coil is connected correctly. The positive terminal will have either a plain white (non-ballast) or pink/white (special ballast resistor wire) and white/yellow (ballast bypass for starting) on it.
