WYZEUP 283 Report post Posted September 16, 2016 Hey guys, Just wondering has anyone wired a aftermarket fan onto their radiator using the factory temp sensor in the radiator and how did you go about it? The car was originally a poverty spec one with no aux fan so unsure if the wiring would be their for the fan either?? Wiring is not my strong point but im trying to do as much myself as possible. so any help would be great Quote Share this post Link to post Share on other sites

Check to see if you have wiring for the Aux fan first, and if not, you end up running 3 cables to the fuse box, crimping some ends and plugging it into the relays. The E30 wiki has a good page for this. Then just running a ground line from the fan to the chassis. Can show you on mine if you want, flick me a Pm.
