The DSE Selecta-Speed wiper motor kit comes complete with the new wiper motor, plus a billet mounting plate, a prewired switch and harness terminated with GM Weather-Pack connectors, and new aluminum dash knobs for the wiper switch and headlights. The kit is specific for each model year.The DSE Selecta-Speed wiper motor kit comes complete with the new wiper motor, plus a bill You don't see many stories on upgrading a wiper motor for enhanced performance. It may not make your car run faster or handle better, but it does offer some advantages over the original equipment. The Selecta-Speed wiper motor kit is the product of Detroit Speed & Engineering (DSE), a firm formed several years ago by husband-and-wife engineering team Kyle and Stacy Tucker. The DSE kit is based on a late-model unit offering seven speeds, five of them with delays. As an added bonus, the DSE unit uses an angle-drive type motor, so it mounts parallel to the firewall, rather than jutting straight out from it like the stocker. So now big-blocks and tall valve covers don't necessitate removing the wiper motor to adjust the valves. The late-model GM motor assembly is mounted with a custom-machined billet aluminum adapter plate and includes its own wiring harness and switch, so nothing needs to be cut or spliced for installation, allowing the car to be returned to stock at any time. The kit's quality and completeness is impressive, and it's obvious that it was designed by enthusiasts with a desire to enhance a classic rather than just adding a gimmick. The following installation steps illustrate how simple it is to complete the conversion. Begin by removing the stock wiper motor. Three small bolts fasten it to the firewall; once they're removed, the unit can be pulled away to expose the connection between the motor's pitman arm...Begin by removing the stock wiper motor.

The wiper arms will have to be removed first; pry them gently from the splined shafts at the point opposite the wiper arm to overcome the spring tension.

The directions include a template for marking the location of the hole. After marking the location, remove the template and drill a 5/32-inch hole. The new switch can then be installed.After removing the old wiper switch from the dash, a small hole must be drilled to locate The only wiring required for installation of the kit involves the ground and power leads. DSE's wiper-motor kit also includes an additional aluminum knob for the headlight switch, so that the two will match. The original headlight switch knob is attached to a shaft, which can be pulled from the headlight switch when the release button on the side of the switch is depressed. We didn't think we could get our original knob off without destroying it, so we obtained another switch shaft (these are the same for many GM cars) and used it with the DSE knob.The only wiring required for installation of the kit involves the ground and power leads.
