Connecting Electric choke
On my 82 F-150 300 six, i've got the electric choke connected to the fuse box, so that when i turn on the key and start the truck the choke is on.
How or, where do i hook this to the alternator like i've seen in other posts? I'm getting this feeling it isn't supposed to be this way... but maybe i'm wrong.
Anybody got any suggestions?

Connecting Electric choke
If the truck had an electric choke from the factory, there should be a single wire pigtail low on the fenderwell on the right-hand side. This is a white wire with a red stripe on my 84, and it has a box connector. Check the voltage at this wire with the engine running, it should be in the 6-9v range. Simply hook your choke to this, and you'll be fine. Running it at a full 12v will work a little while, but will cause the choke coil to burn out, and also cause the choke to pull off too soon. All that power does is keep the choke open when the engine is warmed up, and is calibrated at the voltage from the alternator.

So, Fordsix... it should be on the drivers side of the engine bay while looking into it right? Or should that be passenger side?
If i can't find this wire, i'd like to know which terminal of the old 3 wire alternator is the stator wire, without having to remove it, its kinda hard to see the back of it.
Any more ideas/help is appreciated
P.S. I thought i had the choke wrong....

It's the passenger side. Any time a manual gives a side of the vehicle, it is taken as being the right or left if sitting in the vehicle. I'm a little rusty on electric chokes right now, but I believe that this wire actually clips into it's own socket in the back of the alternator.

Mine 77 is wired out of the alt. wiring harness. I got the correct wire by looking in my Haynes manual in the wiring diagrams. It is the stator wire. I think if you look at the voltage regulator, on the plug, one of the terminals will have a "S" on it. Splice into this wire and run it to your choke cap.

The terminal on the alternator for attaching the electric choke to is identified by the black insulator around it on alternators of this vintage before the internal voltage regulator type appeared.

Connecting Electric choke
I've been meaning to chime in on one of these posts because I keep reading about connecting the choke to the stator on the altenator. My 84/351w HO had the elctric choke wire running from the choke to a drivers' side firewall-mounted box. A few wires lead in, a few lead out, one running to the choke. I suspected my choke wasn't working, and found that the terminal in that box for the choke wire was fried. After a while on the computer, a ford dealer parts guy quoted me something like 40 bucks just to buy the little box. So I just hooked the choke wire to a live wire I found near it (I think the choke is already fried, but that's a different story). Anybody ever seen this? I just bring it up because desperado's setup might have been like this.

My manuals show a choke relay for the 351 HO. One wire goes to the alternator, one to the starter relay, one to the choke, and one is ground. I don't know if the 300 ever had a choke relay (mine doesn't).

I did a little more reading and my manual says there were two types of electric chokes used: alternator powered (~7.2v), and battery powered (12v) chokes. The only specific applications I could find was the 12v choke with a relay used on the 5.8L 4V, and the 7.2v choke from the alternator on the 7.5L.
So I'm guessing if you have a relay, it's 12v. If not it's 7.2v.
