pureboiracer 0 Report post Posted August 29, 2007 i am wanting to put in a electric cooling fan on the e30 to replace the viscouse fan on the water pump. i want to run it through a temp sensor so i do not have to manualy controll when it comes on and off. i have 2 temp sensors on the radiator but they are both being used. not sure what for.,,,, does anyone know if i can piggyback off any of those sensors and the best way to wire it? ie through a relay etc. cheers oli Quote Share this post Link to post Share on other sites
