Update: I tried to do what farmtruc suggested but ran into a wiring question.

I was able to wire the 3 wires to C100 and 1 wire verified light blue at C1 F9 from the original drive by cable cruise control module connector.
Then I tried to do what "farmtruc" mentioned but some wires have been wired different than the 5.3 schematic/ connector diagram states.
C2 F11 has a large gauge yellow wire where the park neautral wire dark green is said to be located. It is currently not in my C2 connector. Also, the D12 yellow/black wire for the starter relay was not plugged into its spot but a pin was installed and wired directly to ground. When I replaced the grounded wire with the called for yellow/black wire I get a no start.
Can a wiring expert please chime in to help me out. Thank you in advance!
