Should be for cruise control or intermittent wipers, depending on location.

Those were primarily used with trucks with A/C or trucks with California emissions, etc... depending on year model and engine. There should be a device on the carb that actuates the throttle linkage.

And you bypassed the "fuel return metering devise" at the carb? Could you post pictures of it? Not sure what you are talking about there. As far as I can tell you may be talking about the emission throttle control solenoid. What the actuator, "Black Box" controls... etc...

First of all....

What is the problem? What are the symptoms? Short description.

1986 F350 with a 460... Electric fuel pumps or mechanical? How many gas tanks?

Next, more detailed information... what have you one already to locate & repair the
problem? You mentioned you replaced a bunch of parts, was that in an attempt to fix
this problem or did the problem arise after you installed them? Be through here, the
more info you can tell us up front, the easier and faster it is to try and figure out.

You might start a brand new thread with a descriptive title, it'll help attract people who
might know something about how to help you figure this out.
