wire in wrong spot?
I had a freind looking at my engine the other day and he notice this wire (marked in red) he says hes pretty sure thats not where it goes, but cant figure out where else it would go. the wire itself has electric tape on it like its been spliced. the truck runs and everything but she does have a bit of an idle problem sometimes. if this wire is in the wrong spot could that be the cause of the idle problem?
thanks in advance

Looks like they tied the throttle stop solenoid to the hot side of the ignition coil. It might work, but it's not right. Disconnect it from the ignition coil, and search for the wire it was originally connected to, it is probably the same color wire even if they cut off the mating connector.

This looks like a fast idle solenoid for an air conditioner. It is hooked to the clutch circuit of the compressor. When you turn on your a/c, it pops out and increases the idle of the engine to keep it smoother. If you don't have a/c, you don't need it. Remove it from the coil, and re-adjust the idle speed of your carb.

that may not be completly right ( todds79 comment)
it may also be an antidiesling solenoid
it gives a 750 rpm idle and when you shut it down it drops the
butterflies closed to about 400 rpm
this prevents run on when the engine is turned off
check to see if it activates with the key
this will cause a poor idle if not activating or wired wrong

It should be hooked up to a connector on the engine wiring harness.
It gets its power from the black throttle actuator box located on the firewall inside the cab,
