I am using the relay board. I jumped from the center to V on the board and also jumped were the relay is mounted. I am running a wire from the board, FIDLE port, to the PWM valve (12 volts). Now the instructions say to put a diode across the PWM, banded end to 12 volt supply non banded to the lead that goes to MS. So this is were I am confused. My plan is to install the diode in series in the ground wire. But which way? I am thinking the banded end to the PWM the other grounded to the throttle body mount stud.
In advance, Thank You for the help.

Re: Ford PWM wiring question
That sounds good to me,please note some Ford Idle valves have an inbuild diode,check at the side of the connection for + and - markings,reversal can lead to sudden death (of the valve)...

Re: Ford PWM wiring question
The point of the diode is to create a loop to short out the flyback spike. Putting the diode in series would not do that.impalakid68 wrote:I am using the relay board.
