ACDelco part # 13592144 is the OEM relay for this fan assembly. Chevy dealer says that there is only one relay to run both PWM fans. I've tried very hard to set it up as it came from factory. There is a 5 volt green trigger wire that turns the fans on from the ECU. System is set for variable speed fans.
