Can anyone advise how to wire it up?

I think one wire to the points side of the coil - what else?

Cheers Chris

It should need a power in, an earth and a pass through from the coil to carry the impulses. That's the one you mentioned.

Case needs to be earthed. Lead from the coil to the bullet connection, switched feed to the 'lucar'. Thats how I wired mine.

Some early versions need to be wired in series with the coil as they use an inductive pickup.
