zgeezer Posted November 4, 2021 Share Posted November 4, 2021 How do I wire my Ls1 engine harness that is wired to allow the engine control module to control two radiator fans. My aftermarket loom is terminated with two relays: one for the low speed fan and the other for the high speed fan. My fan is a two speed ford Lincoln unit. I would like to wire it so as to be controlled by the GM computer. Does anyone have any schematics or photos of the Ford fan being controlled by the GM computer?
