440 Six-Pack Idle Solenoid

[wmiller]

When I restored my '70 Challenger 440 Six-Pack it did not have (in the tons of boxes) an idle solenoid. I have since acquired a working, correct solenoid. Now I can't seem to find out how this critter is supposed to work. Can anyone give me a brief rundown on the following:

1. Does the solenoid extend/retract with key on/off?
2. Where on the wiring harness should I look for the wire and what color should it be?
3. I think I understand the function (to close the throttle blades to avoid deiseling) but any further info would be appreciated.
4. Do I really need this rascal part? I would like to install it to retain originality.

It extends with the key on & drops the throttle closed to stop dieseling as you suspected with the key off, I can`t remeber the wire color maybe green & it should be with the temp sender wire at the front of the engine.
No you don`t need it & it doesn`t have to function to look original

Thanks alot. It sure helps when you can understand the proper function. Will check it out.
