Will the modern electronic e units work with a post war AC Motor, if so can you provide a wiring digram,
The modern electronic E units or circuit boards may work but there is some re-wiring that is involved, I don't know the details.
My advice is to buy an older re-vamped, or rebuilt, E unit from a person or company that will rebuild your older E unit. Or send in your old E unit to be rebuilt. The reason I say this is because of knowing about AC electric motors, the field windings must be powered to produce a magnetic current. The older E units have this provision, not sure about the newer electronic circuit bards, also will a circuit board be able to handle the slightly higher wattage needed to energise the field coils?

Dallee http://www.dallee.com/PDFs/DalleeCatalog54other.pdf (http://www.dallee.com/PDFs/DalleeCatalog54other.pdf) makes electronic reverse units that will work with old AC motor locos. The #400, rated 4-amps, is for smaller single motor units. The #1400, rated 10-amps, will work with larger single motor steamers and dual motor diesel locos.
Wiring diagrams for various styles of AC motors are on the Dallee web site.

The additonal question is--could you install Williams horn in an old Lionel 2033!
It may fit if you remove the original battery holder and horn relay. You might have to drill a coupler of mounting holes though.
The question is whether that will leave room for the Dallee reversing board. I've never done both in a 2033, so I don't know. I've only done it with a 'big brother' 2333, which has more space to work with.

TB II will fit into PW Diesels without a problem just remove the original mechanical horn and find a hot wire and ground it to the frame and you are all set. Use tie wraps to hold in place but please insulate it from everything else. I have done it several times and it works great.
