Just been treating rust and cleaning. I'll be coating the underside with POR15 today or tomorrow, then the modifications can begin. First on that front will be stripping the existing harness down to what is necessary: AC, lights, ABS, etc. None of that connects to the ECM on my year, so it'll be a matter of identifying and eliminating all of the wiring for the old ECM. I'll be leaving pigtails on all of the wires going in to the firewall connector for the ECM; that;ll leave a convenient and factory method of running wires in & out of the cab. Also, I'll start on fabricating a mount for my electric fans. They're factory 9 blade fans & shroud out of a 2009 Escalade.
My plans on oil & trans cooling is separate coolers with fluid flow controlled by a thermostat. Any thoughts on that?
