HI guys, I know this has just about been beaten to death. I'm about to make the swap on my Ram 1500. After much research (I don't want to over heat, or burn up the fan) I came across the diagram on the first page on this site. I don't know why the rest of the diagrams have a hi or lo setting, but it makes a bit of sense. Would suck to burn out the fan cause hi and lo was powered at the same time. It's also been 20 years since I dd anything with components and my math is non-existent and no one had hi/lo and A/C inputs other than a pre-made fan controller....may be the best way to go, but some low reviews made me think otherwise. But I did manage to come up with a circuit that allows me to run the fan from three inputs. Using a Circuit Simulator lo and A/C both kick on the lo speed, hi disables the lo side and kicks on hi speed. Also has a blown fuse relay for both the power and the control sides. I'm not sure if the power fuse circuit is what works best and uses a relay to power the fuse indicator when ignition is on. No reason running the battery down, huh? import the following txt file into the simulator. I'll be putting this circuit to test in the next week or two. We'll see if I have any issues. taurusfancircuit.txt
