Wiper switch compatability?

Witchboard said

Is there a chart or matrix of what switches are compatible with what vehicles? Currently our 64 Barracuda has a single speed wiper switch (part number 2291668), with no windshield washer equipment at all. No nozzles, lines, reservoir or pump. I'd like to replace my switch with one that supports an electric pump as I see there's a complete kit available for an electric washer. I guess I technically could just add a button somewhere under the dash if needed, but that's not very intuitive. There seems to be a ton of mopar wiper switches available, but not sure what would fit.

If you want the factory setup, try to find a '64-6 A-body parts car with variable speed wipers. For ease of wiring and interchange, try to find a genuine '64 model. You'll need the switch and related wiring along with the variable speed wiper motor. The '65-6 use the same motor, but, the switch and wiring are a bit different, but, can be adapted. AFAIK the wiper transmissions are the same between single speed and variable speed those years, but, the '64 transmission pivots use bolt-on wiper arms, whereas the '65-6 use the push-on arms. You'll also need the wiring, washer pump, hoses, T-fitting, nozzles, and reservoir too of course. Early A's used the Jiffy Jet bag and bracket. Later models used the plastic reservoir. All '66 and earlier A-bodies used the remote pump that mounted on the inner fender.
