VR4G63 Posted March 6, 2019 Report Share Posted March 6, 2019 Hi Guru's, What's the easiest way to set up my fans on my G4+ plug in on my VR4 ? The following has been done - Factory fans and radiator have been replaced with new slim line and new radiator. - Wiring to fans have been unplugged. - A/C has been removed from car and unplugged. - A/C temp sensor removed. All other Ecu sensor set has been completed and all running as they should, just wondering what part of ecu we look to tap into to trigger fans to start with ect ? Thanks in advance Quote Link to comment Share on other sites More sharing options...
augusto Posted March 6, 2019 Report Share Posted March 6, 2019 Use the help output wiring relay and output fan configuration. Quote Link to comment Share on other sites More sharing options...
gtihk Posted March 7, 2019 Report Share Posted March 7, 2019 Do you now have one fan or two? Which ECU do you have? Quote Link to comment Share on other sites More sharing options...

Adamw Posted March 7, 2019 Report Share Posted March 7, 2019 If you are happy for both fans to turn on/off at the same time then connect their relay to pin 65 (Aux 4), set Aux 4 in the software to engine fan 1. If you want the fans to switch on at different temps then wire the 2nd fan relay to pin 62 (Inj5), set inj 5 to engine fan 2. Aux 4 was originally the AC clutch and Inj 5 was originally the purge valve. Quote Link to comment Share on other sites More sharing options...
