So, this is a very long thread, but a question that still isn't clear to me is whether a current GM LT4 Crate harness with E92 can support PWM? It appears that only fan relay control is provided (from instruction manuals). Can a PWM signal be pirated off the harness for SPAL brushless fan control somehow?
