TEREX TA64 Knuckle Boom Lift

I've been scouring the internet looking for a service/shop manual for this 1996 lift. All I can find is the parts and owner's manuals. Seems to be very limited results for this model.

Does anyone know if this lift has a direct parallel to another brand/name like SIMON or GENIE that I could look into instead? I'm mainly interested in the wiring schematics, but if I could get my hands on a full manual that would be nice too.
