About a 1986 with a 300 6 cylinder and it's got all the wires coming out of the carburetor for the emissions I think and I ended up buying another carburetor that doesn't have it and I've got the distributor the brain box I guess and coil and all that stuff and I was wondering if I could just swap that over what all do I need to do
This is all the stuff that I've got Hope this is correct can I just wire all this from existing harness on driver's side fender? Do I need to disconnect the computer in the cab somewhere?
Is that we're I connect the ECM?

Reason: What I'm working with
Carb normally has maybe one wire on it, for the choke. You sure you don't mean vacuum lines?
How basic is your knowledge - do you know what parts you have there? Were any taken off your engine? Can you post pics of your engine? Telling you how to hook it all up is gonna take a while. On the top blue bar in the middle is a "search" button. Figure out how it works first, as a lot of answers are going to tell you to 'do a search for XXX' rather than someone explaining real basic stuff.
Ok the reason I'm going this route is because the feedback carb is in really bad shape the truck runs really bad. Does any one know if the combo I have in the picture will work? I have limited experience with ford's but really like what I've been reading about this 300 6. Was going to attempt it today but Its a blizzard this am. Only day off in wks !! Of course. Thank you for all the help you guys on here are very knowledgeable!
From the picture I would say you have everything needed for a running engine. Check the coil - it should say on the side "for use with breakerless ignition" or some such if it is OEM. Points coils are different.
Check out the website gofastforless.com for some good tips. Good luck with your project.
P.S. There is a good chance that your feedback carb is stuck in the 'full rich' pintle position as that is the default condition when something in the EEC system fails.
Thanks for the help anyone want this feedback carb maybe someone wants to rebuild it they aren't ch

I think the harness going to feedback carb has deteriorated bunch of bare wires and yes it's running really rich.
Yes it looks like you have every thing but part of the wiring harness to link the ICM, silver box, and the dist, coil & trucks wiring together.
If you cant find that harness Painless sells one but sit down when you see the price of about $80.
Some have made their own harness also.
I also believe you will need new plug wires but could be wrong so check the caps & wires to make sure.
You set your motor at TDC compression stroke and pull your old dist and drip in the non-feed back one setting it on TDC like the old one was.
Once wired up you can start the motor to make sure it runs and time it. It should run no worst than it did before.
Once it runs you can swap the carb. The only thing I can think of that can get you is if your truck run an AOD auto trans and the non-feed back carb is not set up for the kick down cable.
Now part of the problem is there was no non-feed back carb used with a AOD auto trans and I am not sure how others have over come this.
There is a lot of information on this swap in the 80 - 86 truck area so look in that area for a fix if you have the AOD auto trans or ask the question how to get the 2 to play nice.
