Just for fun, here is the switch. I don't know if you Impreza guys have these or not (I'm not very good with Imprezas, but I know you guys have some cool stuff like intercooler sprayers), so this is my show and tell. The switch is 0-5 in half step increments. I'll post a video after I get it hooked up. I just need two more connectors to get them working.
