Up for sale is a new style PRS7 wiper switch - P/N 39156B. You can buy this switch new from AES in the UK for around $80 with shipping. This switch has been modified by adding an extra terminal for slow, fast & park. It works perfectly when wired with the included schematic and relay. I am even including a new 5 pin connector to plug into your wiper motor and including the correct knob. The knob is not engraved and will need to be drilled if you want to use the spring loaded button on the switch actuator. Free shipping in the contiguous 48.
