Intial tests have not proven fruitful. I have attempted to send the 080 messages at 80km/h and the steering wheel static, but the pump has not spun up. Yet. I have quite a few more things to try.
Yeah, I was cautious of the pump spinning up on it's own. I was careful to mount it and clamp it down before I applied any power, so I didn't have any expected launches into life. The M10 150mm glavanised bolts from bunnings are just long enough with the copper pipe cut to hold it about 5mm off the ground.
Since I'm getting broadcast and PID responses I'm pretty confident that the wiring is right. The rest is up to me to sleuth the message that turns it on.
