Hey guys and gals,

If you're like me you're nuts. LOL. I want variable intermittent wipers on my EP so bad. I hate being in a rain fall where the intermittent speed is too slow and the slow speed is too fast. So, I want a variable intermittent speed to set it to "the sweet spot". How am I going to do it? Simple. Remove the EP3 wiper switch and install the RSX switch in it's place. That's not it though. There's a little bit of wiring involved. You have to add two wires from the RSX wiper switch to the EP3 multiplex control unit connector "X" pins 3 and 4.

- Phillips screwdriver
- Flat screwdriver
- Electrical terminal picks
- wire cutters / strippers / crimpers
