Very Rare Mopar Part...Does anyone have more info?

[FFGREG]

I purchased an NOS Short Wave Converter from the 50's. It's a Mopar part number 1594455. I found a Google thread on a site which stated that the person who had a car shipped to Mexico from Chrysler, would have had this in the trunk of the car, for the dealer to install, as Mexico or (Europe) didn't have the same radio bands as the 'states. I would like to know what year and Model Mopar vehicles this would have been correct for, and any info on technical diagrams or instruction pamphlets, or pictures from Chrysler accessories books. Ok Sherlock, what do we have here? X100 or X100C are other numbers associated with it. X100 on the Case, X100C on the box.

Viewing a thread - Mopar Model x100, what is this ?

I've never seen one of those before, but I've gone down a rabbit hole on Mopar radios before, while trying to figure out if there was some way to add aux input to my '63 without butchery. Here's what I can see:

1. The 4-prong cable looks a lot like the cable for a Hi-Way Hi-Fi. Compatible radios have a receptacle on the back. I assume the prongs would be something like power, ground, and audio? I've tried to find a pin-out diagram to understand what each prong does, but have never been successful. Since these systems were completely analog, I think both this converter and the Hi-Fi would somehow just output their audio signal, which would trigger a relay inside the radio that would cause the sound to route from the input instead of the AM receiver. (I'm just an amateur, and not even very good at this kind of thing, but that's what I understood from reading a pdf of the service manual.)
2. The other cable is an antenna output, which probably plugs into the back of your factory radio to allow pass-through
3. There looks to be a hole in the back of the case where you would connect the vehicle's antenna. As above, I assume signal would travel a path of antenna -> converter -> factory radio

Thank you for the input. My short wave converter seems to have been manufactured in 1955, according the Mopar part #. So, perhaps used in the 56 Imperial/DeSoto Chrysler Car lines. I haven't tracked down the mounting bracket, nor the operators guide. That all seems to be intuitive, as the radio would have the 4 plug, input, and the other feature ( just as an FM converter would have) antenna pass through. Plug the vehicle antenna into the Converter, and the pigtail with the motorola ant. plug into the radio. Research continues on this rare part , thank you for your input!

My 1955-58 parts manual says that it was available for all the 1958 cars.

Does it have the part number listed?

@FFGREG @Big_John @58Belvedere @UGW Hi everybody. I need to apologize. I wasn't paying attention. I was looking at the listing on the AACA site with the part number in the manual which is 1779144! The 1779144 number is what's listed for the 1958 cars. I am guessing that yes by the part number yours may be for the '55s. Is it 6 volt because the '55 cars were? I had the radio out of our '56 Plymouth that we had in the late fifties and I think it was early production because it was a 6 volt radio with a 12 volt to 6 volt transformer! If I remember, tomorrow, I will look through the collection and see if there is a reference in an accessories catalog. I do not have a '55-'56 parts manual.
