The wiring on the Mazda pump looks identical to what I have seen on the Volvo pumps. It may or may not operate the same, but there are guys working on a solution. I have another idea that may work, but I have to get up the nerve to take the whole thing apart and look at the electronics, not the input side, but the motor side. I know the input side is looking for certain codes to come on the CAN BUS, but the output (motor) side might simply be a square wave that varies in frequency. Everybody that I've seen is looking at the BUS signal. In the end, it matters little because I got a 1-year warranty with it. Won't get cash back, but I would get credit towards something.
