We didn't wire ours that way, all three wires into the EDIS, it works OK (don't actually see why you couldn't use the chassis as ground but we just followed the MJ manual to the letter)

Is your edis grounded ??

edis is grounded and i just tried wiring the ground from the tps to the MJ and got the same result.

should the Vref (white wire) have a voltage or reading of some kind against the ground?

right, i have taken a +5v from a spare on the MJ, so the sigal from the tps to the mj is 0.69v when closed and 2.19v when open... that should work right????? also should i be worried that where i should be taking the +5v isnt working?
