VR4 duel fan wiring


Recommended Posts

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

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.
