ASAP Choke Control unit! NEEDED FOR MY DAILY
You have to find it NOS. they aren't repopped. They only send power to the thermostat when the engine is cold. Like I said, most of them quit working shortly after they were new. The only thing that will happen is the thermostat will take slightly longer to open.
I've got the original one on my Challenger. I doubt it works any more. It's there for show only.
I just did a search and looked on E-bay. There are a few on there if you really need one. I think the big block cars used the ones with the extra resistor on the side.(like the above picture) My 318 car uses the one without the extra resistor.
