OK, I am trying to get my 750 hooked up on my sprayer, I have a foot switch for a master, running through a 4 prong relay then into the back of the 750, My problem is that its working backwards, in other words when my foot switch is off it is mapping and when its on it stops mapping. I've tried switching the wires around but it stays the same, any ideas as to what I'm doing wrong!? Thanks!!
