I'll try and add clarity to my previous post:
The FPCM switches the pump's ground either directly to ground - or to ground via a "dropping" resistor. If it goes directly to ground you get full power, if it grounds through the "dropping" resistor you get less.

The problem peole have found with voltage drop is that the stock wire causes too much of a voltage drop so they 'hardwire' a cable with a higher current rating and use a new relay while they're at it.
