Does anyone know where this electronic choke control would have mounted on a 73 barracuda.

[Flathead31coupe]

It has a lead wire of about Five or six inches that goes to the choke.. Does it seem like it would be too far away.

Under the coil bracket plate.

The electric assist choke heater control assembly is mounted on the intake manifold on small blocks or on the head on big block and slant six engines. The following image shows one mounted:

On the small block engine, the control assembly mounts under one of the coil mount bracket bolts.

1973 engines used the Chrysler number 3656730 shown in your picture.

Here it is on my 73.

Thanks I appreciate it... what book is that you are using as a reference thanks.

Also the wire that goes from the switch to the choke is in pretty bad shape.Is there a replacement?It looks like it is a type of cloth wire?

The wire from the electric assist heater element in the choke thermostat is insulated with two high temperature, woven fiberglass sleeves. One sleeve covered the wire conductor, and the other sleeve overlaps the first to cover the element connection.

The wire and/or the sleeve can be replaced. The wire is crimped to a 3/16" spade terminal for use on the 3656730 control assembly. The other end of the wire is crimped to the element connector, but is not as simple of a crimp as the terminal.

If the wire conductor is intact, it will continue to work, but with a risk of shorting if it touches ground or other exposed wiring. The sleeve(s) can be replaced by removing the spade terminal, adding new sleeving in the manner of the original and re-crimping a new 3/16" spade connector. High temperature, woven fiberglass sleeving can be found at McMaster-Carr and other sources.

If the wire is bad, or broken off, a replacement high temperature wire with similar insulation can be attached. This wire can also be found at McMaster-Carr.

Alternatively, aerospace grade Teflon insulated wiring could be used. Note that even regular automotive PVC based wiring can be used, but will likely become brittle over time due to the heat in the area. Silicone jacketed wiring could be a decent compromise.

NOTE: If replacing the choke thermostat itself, later versions for the revised controller, and many aftermarket replacements have a 1/4" spade terminal rather than the 3/16" terminal. This is easily spotted because the 1/4" insulator is black rather than red. The terminal connection will still work, but is not ideal.

Wow great information...thank you
