The original choke is vaccuum operated, so no original choke wire. Anyone who has done the weber upgrade know what to do here? Should I just use a standard 12v feed from the battery?

No, for an electric choke, you want a SWITCHED 12v+ power source going to the choke, so that its closed with the key off, but once you turn the key on, it slowly opens up.

The other wire goes to ground.

Actually, the vacuum is the choke pulloff mechanism. All the 22R chokes were electrically heated (20R still had the water choke), so there is a wire in there somewhere. On an 85, look for a round, green 4 wire plug on the passenger inner fender near the carburetor.

should we move this post into the weber tech post that up until this point seems to have been ignored by the majority? (when posting questions)

it occured to me after I posted this that it might be nice if that weber tech post started accumulating helpful info and I'm willing to supply stupid questions and pics. <img src="/forums/images/graemlins/notooth.gif" alt="" />

I do have further questions on this subject but I would like to supply a couple pics for reference. thank you for the info so far guys.

OK so here's a picture of the truck side of the plug.



I took the liberty of labeling it the opposite of the carburetor side as illustrated in the picture



And then here is a picture of the connections on the side of the Weber:



So my question to clarify is this: Are you saying that I should connect the fuel cut (+) terminal to the choke terminal? (labelled "1" in the picture) And the instructions included with the Weber say to connect a "jumper wire" to the fuel cutoff solenoid (labeled "2" in the picture) Would that mean doing what I have done with the yellow wire? (labelled "3" in the picture) There are no other terminals on the carb anywhere, so basically my question is just plug (1) into the fuel cutoff (+) terminal?

Well, you could do it that way, but the way the factory "computer" operates the fuel cut wouldn't be ideal. Assuming you still have the 2 vacuum switches hooked up on the passenger fender, the truck will cut power to the fuel solenoid when slowing down over 25MPH with the brakes on to conserve fuel. Ideally, you'd hook the choke wire to the "Coil housing +" and the fuel cut to the "Fuel cut +"

I don't have the fuel cut solenoid on my 32/36. all I have is 12v going to the choke spring, and that's it.

at least I'm pretty sure it's 12v. if I'm not mistaken there's also 6v wire(s) in that bundle as well? can't remember. I can read it out for sure if necessary.

I made a very technical wiring harness <img src="/forums/images/graemlins/rolleyes.gif" alt="" />
and then hooked it up...





In addition I found that I still needed to plug a couple vaccuum ports coming off the intake and i had a vent hose and the fuel supply line crossed. ( <img src="/forums/images/graemlins/scared.gif" alt="" /> that can't be good) had fuel coming out the other vent line that's supposed to go to the first charcoal canister. that tripped me out...
anyway, she fired right up and was running very smooth. It's been a long strange road to get to this point, I'll tell you all the whole story in another section of the wire someday, but the engine change out and the offy intake / weber might not have been the best idea to do all at once, but whatev. I'm coming around the final turn now. I think I have the vac advance hoses figured out for the distributor, and if I do, I will show where they go so that others may have a look. thanks guys.

vacuum hoses are pretty simple, though it took me years to figure out that my truck exhibits better driveability and fuel economy with manifold and ported vacuum on the distributor as originally intended. I've seen some errors in various Weber install documentation where they recommend "jumping" a single vacuum signal. this is incorrect.

any idea where to get those metal plugs that screw into the intake?? I think I need one more. thanks for the show and tell. that will be very helpful <img src="/forums/images/graemlins/kewl.gif" alt="" /> do you still employ both charcoal cans? and also, is that an aftermarket distributor?
