In LOW, power goes from the switch (A) to the motor (L). The 2sp concealed wiper motor diagram doesn't give colors, but requires its wiper switch be grounded.įor the 2sp non-concealed, basically, at OFF, power comes from the switch (P1) to the motor (P1), through the park switch, out P2 back to the wiper switch (P2), from switch (A) back to the motor L. The 2sp non-concealed wiper motor shows a L (brown) to resistor, P1 (blue), P2(green) and H(red) connection but I don't seem to have full 1973 Dart schematics. I seem to remember, but I could be wrong, that my old 1973 Dart didn't reverse direction when I turned it off - it just completed the cycle and stopped. I have my 1973 Dodge FSM in front of me - I don't know whether you have concealed or non-concealed wipers. In the 2sp Mopar wipers, the only tricky part is the parking. All you need do then is move the pin from the old housing to the correct slot in the new housing.Īgain, I can't stress consulting the FSM enough, but don't assume it matches anything anymore. The FSM shows which contact is where on the 2sp switch housing. It would also be good to record where they go through the bulkhead and their colors on each side for future reference. If should be easy to find the right switch connector housing for the switch the contacts are easy to remove and move from the old housing to the new housing.įirst, you must trace each wire from the motor to each pin on your current switch connector and record it do NOT trust the color codes as they quite possibly no longer match the FSM. The 2sp system is *much* simplier to deal with, so you might want to return it to a more-or-less stock 2sp system. While I have mixed & matched parts of 2 and 3 speed systems over the years for a number of the Tidewater Mopar Club giveaway cars ( ), it's tricky and I generally don't recommend it unless you know what you're doing AND have a FSM for the right year in front of you AND take time document of what goes where. The 2sp system uses a different wiper, harness, and switch than the 3 & variable speed system.
