Yesterday I traded my soft top and some cash for a hard top. Since my jeep was factory soft top, it wasn't wired for defrost or a rear wiper. Has anyone wired up relays and toggle switches for this? I found this http://www.quadratec.com/products/11190_51.htm but it's only for 07-11 and it looks like a lot of trouble. I would like to avoid any computer issues.
