Hi, have a one piece case 4L60E KCDO89. 1996 K series 5.7L which I want to install in a 1989 K1500 with a 700R- just for easy fitment. I also want to convert to a 24X engine management ecu with a trans controller, engine will be the existing SBC gen1. Choices are 0411, Halthech Rebel, Holley Terminator Max, or ??. A piece of info I came accross... even for the 0411 the harness and electrics would have to exchanged for 2002 4L60E, and the aftermarket ecu's seem to touch on 2008 electrics.....is this true and can it be done. Current pump in core is PWM which I am not interested in utilizing. Repinngin is not a dealbreaker for me.
The Holley seems more concerned about the connector pinning with a comment about pre and post 2009.

The Haltech seems more concerned about not being 4x4 and 2006-2008.
