FEEDBACK SOLENOID WITHOUT WIRES?!?!

This is my first post so let me know if I'm posting this in the right area....
Well I have a 1985 Ford F-150 Inline 6 (4.9). I removed my carburetor and rebuilt it. I noticed the feedback solenoid does not have wires coming from it and no wires laying around that would plug into it.... I have searched everywhere online to buy one but no one carries it!!!

I also need a new EGR PIPE but again the only one I can find online is for a
V-8!!!

Lastly I am also in search of a BOWL VENT SOLENOID but AGAIN the only one I can find online is for a V-8!!

Any input would be greatly appreciated...Thanks in advance

Welcome to FTE, you're in the right area.

Can you post pictures? I'm confused, I think you may be confused. Pictures will make things LOTS easier.

You'll need to upload 'em to a picture hosting site or FTE Album you create, then use the IMG code to make 'em show up inline in a post.

the first thing i would do is check if you're required to take an emissions test in your area. if not, your best choice would be to swap out your carb and distributor to a conventional system found on 83-earlier trucks, as the electronic carb of the 84-86 can be a real nightmare. there are tons of posts on that side of things.
but if you have to stick with the existing system, there are a number of guys here who know all the details on it, i'm just not one of them

Rockauto have the 300 vent solenoid.
They don't list an EGR pipe as such, or the feedback solenoid.

Remove the feedback vent solenoid from the carb.

The "can" on the bottom is removable, slide it down and then off.
You will see wiring connections, where the can with the wires connects to the relay wiring. If the can isn't installed right the contacts will not mate correctly.

You might be able to fix/patch your wiring.
At this point test the relay with 12 volts to see if it even works.

You can just drive the truck "as is" ... most folks don't fix the feedback system if they don't have to. It is not cost effective.

This is true, but will cause driveability problems. Computer in limp home mode, no timing advance, and poor fuel economy to name a few scenerios.

If switching to a DS-II system for example, the carb should be replaced with a non-feedback type.

I would suggest the original poster to take a picture of his distributor as well, so we know what ignition system we are dealing with. We may be dealing with a half converted system already, or previous owner hack job.

Pictures would help us to diagnose this problem.
