Hi again guys,

I've searched exhaustively and got nowhere! I'm running megajolt and need to hook up the tacho on a standard three clock dash.

Two connections as far as I can see, a spade connector and what looks like a male bullet connector. What goes to what? Or have I missed a connection in the loom?

Tried Haynes, but the wiring diagram wasn't very helpful....

Thanks again

Ben

Bullet is the tacho signal, spade is 12v switched on the ignition

The spade doesn't come from the coil. Its a white wire which is ignition switched. The bullet is white/black and ordinarily comes from the coil negative to provide the signal.
