The Spyder comes with a rectractable hardtop that is actuated by operating switches that are mounted in the floor console. I decided to automate the top control by adding an aftermarket alarm system, Audiovox APS-996a, which has multiple auxilliary channels. The extra channels are used to drive inputs to a
custom designed controller that is wired into the actual switches. With this system, the user can remote control the top operations. I also implemented the remote start feature and added a neutral safety circuit to protect against starting in gear.
