Hmm.
Since it is a IIA, there is precious little of the electrical system that
has to be converted.
Your truck has a generator on it, or an alternator? It is definitely neg
earth if it has either a rover alternator, or a bastardization.
check out the coil leads. The small, 12 volt ones, not the fat cable. A pos
earth will have the negative leading to the ignition key, positive to earth,
through the points, right? But, then again, you knew that, right ;-). The
polarity should be written on the coil, if not....

That should give you some insight.
If in doubt, just convert the bloody thing!
