Wiring a single fan to work with the oem ecu and function

[ChristianMikey]

Hi I have a 2021 Mustang GT. Car had an otr intake and I am currently running an eco boost radiator. Car has always ran hot and can’t enjoy driving the car in the heat. I was looking at switching over to an aftermarket dual pass 4 core radiator. The radiator is smaller in length but thicker. I will only be able to run a single fan. The fan I was looking at running will be an aftermarket fan. The fan has a ground and a power. Oem harness I see has 4 pins into a plug then splits off into two different plugs with both a power and ground for each fans since the factory system has 2 fans. They also work low speed and high speed. I was seeing if anyone has wired up something Similar and they can give some input on it. I’m not worried about keeping the low speed just high speed and I want the fans to automatically turn on and off.
