Follow along as Detroit Speed Engineering Assistant, Peter Bruschi discusses our 1973-83 GM Square Body C10 Selecta-Speed™ Wiper Kit. Voted Best New Product of 2019 in the Electrical category by Goodguys, this is the first-ever aftermarket wiper kit available for the 1973-83 GM Square Body C10 platform. As with all Detroit Speed Selecta-Speed Wiper Kits, this kit contains a low profile, 7-speed wiper motor (5 delays, low speed, and high speed), rotary switch, adapter plate, and wiring harness. The laser-cut steel adapter plate mounts the wiper motor to the stock firewall bolt pattern and requires no permanent modifications to the vehicle. Specific to the 1975-83 Kit is a LED Switch Plate which allows the driver to adjust the brightness and clarity of the illuminated wiper icon to match factory or aftermarket gauges.
