It can be surprising how often you can be absolutely positive about
something, then find it wasn't as you expected. Nothing like proving it.
There will be no harm swapping the pickup connections at the tach, and
it's worth trying as someone may have swapped them internally for some
reason.
Swapping the 12v and earth is a little more tricky. With electronics
reverse connection can sometimes blow the semi-conductors, so it's a risk.

That wire comes directly from the tach; I wired that myself as
well as the one wire going from the fusebox to the tach. So I
can just about guarantee that if I break that circuit the
engine wonâ??t run. I have not yet tried â??rappingâ?? the
