Doe's anyone out there know how the Idle Solenoid gets wired. This is a 2 wire solenoid with one positive wire going to the back and a secondary ground male terminal on the hex head of the plunger, which is brass and adjustable. We looked at the car and even though there is a blue wire attached to the back....it is going to ground. So it actually seems like the solenoid is hooked up to ground on front and back. Looking for how the wiring should actually go...where and how do we pick up the positive. The shop manual isn't helpful. BTW...the hex head nut that the brass fitting is attached to is insulated so I believe the ground is picked up from the brass fitting touching the adjusting screw. Thanks
