Alan:
If there is a 'thing' under the bakelite cover, and it is a capacitor (as it
most likely is), the pump can be connected either POS or NEG ground. If
perchance someone has installed a diode as the arc suppression device, the
pump will be polarity sensitive. You would then have to reverse the diode
connections in the pump in order to reverse the car's polarity and still use
that pump.

to neg ground
Hi
First test. Open up the Bakelite cover. If the pump has "things" in it
connected to the points it can matter. If you just find plain points it
doesn't care about polarity.

BJ8 and a few more things with SU pumps.
I have one of those converted to electronic switching with negative ground.
