Electric choke thermostats need 12v power. Less may work, but the choke will open slower than it should. 6v does not work. Use any 12v source that is hot only when the key is turned on.
Putting a fuse in line with the thermostat is OK, but the thermostat will work without one.
No resister should be used in line with the thermostat.

Which conversion kit do I need?
Choke conversion kits are matched by original application, start with the application catalog here and select the 'Electric Choke Kits' sub-category at the top of the page.
My carburetor or manifold isn't original, or I don't know if it's original. Can you still recommend a kit?
We can make a recommendation based on the application, or by comparing the existing choke setup. We cannot guarantee it'll fit. With integrated chokes, typically matching by comparing the existing will do the trick. Divorced choke conversions mount to the manifold and use a rod to connect to the carb. There is no way to know for sure if it'll fit correctly without trying it.
Can I replace my divorced choke?
Yes, conversion kits are available for divorced and integrated chokes.
My replacement manifold does not have a spot for my divorced choke to mount, can I use an electric choke conversion?
Yes and no. The mechanism for the conversion kits on divorced choke set-ups still mount to the manifold using the bolt holes for the original divorced choke. We have had customers successfully modify or make a mount for their project, this isn't something that we offer as a service.
Do you have a conversion kit for manual chokes?
No, we are unable to provide an electric choke conversion for an OE manual choke. The choke housing must be installed. The conversion kit is only replacing the choke thermostat.
What kind of power source do the conversion kits need?
