Am going to wire up my cranshaft sensor and use the megajolt. What wire is the + and what one is the negative? Is the top position of the cranshaft sensor the + or the -?
thanks

I dont think it matters which way round the wires go.

On the sensor the lower pin (furthest away from the mounting hole) is labelled 2. This is neg so the top pin is pos.

If they are the wrong way round it wont start.

Oh well i maybe wrong.
