Of the remaining 2 leads, one should be for positive 12v feed which can connect to any 12v supply that is switched by the ignition. Ideally I would add an in-line fuse just to be belt and braces.

The other lead goes to the coil. Now, is it the +ve side of the coil, or the -ve side?? Can't remember! I'm pretty sure it is the low tension side of the coil. Someone will be along soon, I'm sure...
