Default gen iv LS3 wiring

What I got is a gen iv LS 3 connect and cruise crate motor. It is being installed in a 1968 conv chevelle. I have American Auto Wire Update kit and Dakota Digital VHX dash I am installing. Anyone match these together? What do you need to use and not use on the GMPP harness?
Thanks

What are your exact questions?

You have a American Autowire classic update harness, Dakota VHX, & a GMPP connect & cruise?

List the wires on the engine harness that you need to terminate & I'll tell you what to hook them to.

Default interface

highly recommend the BIM-01-2 - ODB II/ Can Interface Module from Dakota Digital. plugs into the interface, connect all gauges, can display all parameters (trans temp, etc)

With my 1965 Buick Skylark I kept the two harnesses pretty well separate. That being the chasis/body harness and the motor harness. Power and ground being common and some of the gauges went with the motor such as the tachometer, oil pressure and water temperature.

I used the third brake light wire on the AAW harness for the converter lockup control on the GMPP trans harness.
