This last photo is a picture of the Motorola dash control I am missing.

I would try eBay.

I would try eBay.

Ebay is where I found the picture of the dash control. BIN for $140 or best offer for the two parts. Not working, trashed wires, lots corroded connections inside. Several other trunk units but none with the dash control.

Turbo looking at your reverb from the 4 pin connector side it connects like this:
If you want to bypass the transducer (reverb spring) jumper across the top two points. I’d blow out all the dust inside and look for burnt resistors before powering it up. Also check power to ground with an ohm meter and make sure it’s not shorted prior to firing it up. You don’t need the fancy control module. You could just use a DPDT switch to switch the reverb between reverb and radio. Let me know if you want me to check it out. I’d be glad to.

So are you talking about a switch like this?

Also assuming these old reverb units took speaker level input, wouldn't you also need a fader control for front to rear output?

Next question, what is the transformer doing in the Motorola dash control? The picture on the unit shows which wire to cut open for different speaker's OHM level used with the original mono radio.

Does it look like the reverb has two separate amplifiers?

I'm thinking about sending it to you. Part about asking you questions is to get your post count up!

17 and counting.... By the way, Welcome to the forum Jim!
