It's also called a "wiper governor" if you are researching. The normal retail parts stores do not carry this module because it's relatively old technology with a soldered circuit board. The price at the local dealer for this part will be around $150. One great option is to find a local salvage yard and pay $20 for the part. The module itself is a black box approx 2"x2" square; 1" thick. It includes two, 6" long, wire harnesses that have female plugs at the ends. One of the harnesses has a red plug that connects to the wiper switch - the other harness plugs into the main power supply. The black box is screwed/bolted to a rigid metal frame with a single fastener. The box has an imprint on it: "Do Not Drop" due to the fragility of the circuit board, I suppose. When you install a new module into your truck, you may consider NOT reattaching it to anything rigid - just let it "float" among the wires so that the bumps-while-driving don't cause any trauma to the soldered joints. Once you sort out the configuration, this is a relatively painless R/R. Also, the salvage yard modules seem to come with the wiper switch attached. So there you go - a fundamental description from a new DIY mechanic.
