check the 3wire conn. right at the shut down sol. check both sides each wire I cant remember the colors and my wife has it right now . one is a grnd. one is a pull up -start the other is run I believe your looking for the biggest wire awg #12 or 10. CAUTION DO NOT LEAN ON THE KEY TO FIND THE RIGHT WIRE,THE SOLENOID WILL BLOW UP. The conn . is a dodge deal and as much as I dislike fords their conn. for the same sol. is much more available and a better design. I can prob. get the part #s for you if this conn. is the problem. A hand operated is much more reliable. A spring holding it open works in a pinch except you have to get out and open the hood to shut her down,have a nice day ,Ray
