Okay just did another lab test to confirm what I thought you supply power to both side wires the value works by increasing the voltage on one wire only so it taks over. That's why the manual talks about variable votage. I made this little pot but last ime it didn't work because I had the neg & postive around the wrong way. I just retried it and it worked perfectly. It simple switches the voltage down on one wire and up on the other when you turn the pot, in the centre positon it inspite of voltage to both side wires the valve sits in the "At rest position". Now if I want I can totally control the idle from in the car.
