Hi Guys,

I'm setting up a universal progressive diesel system on my 91 7.3L F350. As you know these trucks don't have a MAP I'm adding a 2 bar sensor. What I need to know is how to wire it up. I know that the grey wire is used to provide 5v to the MAP & the green wire gives signal back to the controller but which terminals do they go to on the MAP. The 3 pins on the MAP are marked C B & A. What goes where??

Thanks,
Todd

Thanks dvldoc, my wiring diagram showed the MAP but didn't label the pins.

Cheers,
Todd

dvldoc, Just had a thought, you've never had any trouble with the controller or wiring handling the current draw of the pump? I would have thought you'd need to use a relay & use the blue wire to switch it, particully if you had the solenoid in the circuit as well.

Cheers,
Todd

The controller has a 30amp Mosfet chip on the board. But if you do want to add a relay there is nothing wrong with doing so.

But you need to put it on the controllers Red power supply wire not the blue wire.
