[DeTomaso] positive ground

[Gray Gregory]

Thanks Roger,

That does sound pretty simple. I assume dynamo is British for Generator? :>)

If I did that would the starter work without any modifications?

Hi  Gray
The easiest thing would be to reverse the polarity of the car, this is fairly simple on an old car that is running a dynamo as opposed to an alternator. 
The big thing is to reverse the polarity of the dynamo.
To do this , take a wire from the + lead (after reversing polarity and flash it for a couple of seconds to the large terminal on the dynamo the D terminal, reverse the coil leads and from memory I think you then have a - earth vehicle Regards Roger C . UK

It never dawned on me when I ordered it that like most British cars of the day it is a positive ground system. So the question is how do I hook this thing up? Do I just reverse the wires on the coil (red wire to - black wire to +)?  or install as per the instructions? Or throw in the towel and stick to the points?
