Default Related question
In a related question, I'm using the stock ZR1 intercooler (charge coolant) pump and it has a two prong connector (just 12v power and ground). The GMPP LS9 harness has three wires (which are 12V, PWM signal -- J3-42 lt. blue/white, and ground)

The stock ZR1 runs without a PWM-controlled intercooler pump, and the GMPP LS9 harness has a PWM connector for the coolant pump. Why are ZR1 LS9 and the GMPP crate LS9 wired differently in this case?

Any insight or help is much appreciated!
