Having read Dan's reply I can offer some newer insight.

Dan apparently replaced the hot air choke, that allowed hot air from an
exhaust manifold stove to enter the choke chamber through a metal tube,
with an ALL ELECTRIC choke replacement, but still left the hot air tube
connected. This has provided TWO heat sources to the bi-metallic coil,
and I don not know if Dan's replacement included changing that coil. One
is heated by hot air, the other by a heated wire. You would have to
check a Holley dealer's parts manual to determine if the bi-metallic
strips are the same.

In EITHER event, you can only use 1 heat source. Preferably the one that
matches the bi-metallic spring.  If BOTH heating sources are applied,
then the choke will open too fast, and lean out the carb too soon, from
a cold start. You need to check out the part number, with the electric
add-on with the original hot air, and use the correct heat source ONLY. 
there never was such a thing as an electric "assist". It was one, or the
other. I am not certain, but I believe that there is only one spade
terminal, with the ground through the carb body and mount studs. If
there are two, hook them up as Dan suggests.

The hot air choke outer body is different, as it has the threaded
fitting for the hot air tube. If you have that, and have confirmed the
coil is the same, just do not connect the wire(s). If you have an
electric choke peculiar coil, disconnect the hot air tube and put a plug
in the housing, held in place by the tube holding fitting.
