Hi Sorry Guys...started a new business since my last post and been busy...havnt been dropping into the forums lately. I have had a few members PM me...which means I get an email, and I have responded to them. For anybody else, the modules are $105 each inc postage. The installation is quite easy, but its not just plug and play, some basic mechanical skills are needed - the people who have bought them so far have had no troubble with the instructions supplied. Each module will control 1 window, so if you want to control just the driver, you need 1, for the front windows only you need 2, and for a sedan its 4 to do all the windows. From memory all the people I have spoken to so far have only done the drivers or the front 2 windows. I have about 10 left at the moment ready to go, but I can make another 10 without ordering more stuff from China very easily. If anybody is interested just PM me so I get an email to alert me. Cam
