humanz 3 Posted October 16, 2015 Are the pins positioned like |_| ?? If so, as far as I remember the middle flat one is the 12v. Maybe someone else will get back to you before I check this evening. The other two will be for the low and high temperatures. Share this post Link to post Share on other sites
