Adding a Choke Thermostat to a Motorcraft 2100

Hi, I just bought a choke thermostat to convert my manual choke. The choke I bought was Choke Thermostat by GP Sorensen - Part 779-1525 - Advance Auto Parts. So, I have a question...I found out how the choke thermostat mounts...it says climatic choke on the top and there is a place to run an electric wire to it...do I need an electric wire going to the thermostat...and where do I run it to/from? Any help on this matter would help...also, how do I line the choke thermostat to where it's supposed to be? It came with no instructions and I've never messed with it before.

Thanks,
Patrick

It should be a blue wire with a brownish connector at the end coming from the firewall, ill get a picture up later, hope the PO didn't cut it.

Oh, beechedjeepyj you're always here to help. So, I bought a Carter climatic thermostat...I know that it has to be hooked up to the ignition (I would appreciate a picture, thanks)...but can I just ground it straight to the carb?

Sorry its a extreme close up of where it connects, that wire just goes into the loom of wires at the firewall. Not to sure of what it does from there, you'll want to tie it into the ignition relay so it only draws power when the engine is running.

Can I just connect it to the fuse box to something that is only on when the ignition is on...like the wiper motors? Will that work?

then your wipers need to be on for that to be on. and the more you turn the wipers on the more it will have just connect it to one of the fuses near the bottom left of the compartment. i connected a dome light to one for then (forgot which one now) but just find one that you don't use or if you have an extra slot well there you go thats all you need. (BTW the awesome light i fixed for my dad well he broke it...)

I'll give that a try and let you know. Can I ground the thermostat to the carb (if I'm not mistaken that's like grounding it to the body isn't it)? There's a mounting bracket that has plenty of room to put a release for the grounding wire...is it recommended?

Meant mounting screw, not mounting bracket.

so that wire to the electric choke should have voltage all the time when the key is on? if it's on all the time then what disengages the choke after its warmed up?

When it warms up, the butterfly opens...you want the butterfly open the whole time the engine is warm. When you turn the key off, the coil inside begins to slowly cool down and closes the butterfly...the colder the engine, the more closed the butterfly...the warmer the engine...the more open.

Hey did you ever get it working? I found out that the electric choke is tied into the oil pressure switch.
