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.

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.
- Link for McMaster-Carr: High temperature wire

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.

The following images show the original wire and sleeving:

Cool ty

So I am putting together.A basket caseventy three barracuda original parts.. What would be the suggested factory service manuals?I would need that would be good to have as reference...

The 1973 Plymouth/Chrysler/Imperial factory service manual is the primary reference for your car:

When I got this set, they were still available from Chrysler for $10, but that is long gone. Look for them used, or possibly reprints. It is a two volume set.

mymopar.com has service manuals for download, but not the 1973 Plymouth manual. It does have the 1973 Dodge manual in which a lot will be the same including the engine, transmission, axle, brakes, ignition, charging system, and more. Some dimensions, electrical, and other minor differences will be found in the chassis volume. The body volume has more differences, but still usable in some cases.
- 1973 Dodge Chassis Service Manual
- 1973 Dodge Body Service Manual

NOTE: These links are compressed PDF in zip files.

The 1973 Parts Catalog is the second useful reference for looking up part numbers, part cross referencing, diagrams, and more:

These were once available from Chrysler, but now used is the only source of original printed versions.

mymopar.com has the 1973 parts catalog for download:
- 1973 Chrysler Parts Catalog

There are other publications around that can supplement these, including Chrysler training documents, separate service literature, technical service bulletins, sales literature, data books, etc. Many of these are not commonly available, but Hamtramck Historical Virtual Library has a lot. The Chrysler Master Technician Service Conference (MTSC) documents are also available at mymopar.com. These are more general training subjects but can be helpful to understand specific aspects of these vehicles.

Faxon literature has assembly guides which might be helpful. Unfortunately, Faxon plasters the diagrams with annoying watermarks, which can obscure some details, as well as faded print from the original drawings.
