I told them it was deleted and they said ok...but they won't write the ECM until they talk to me. Almost everyone is deleted around here so I guess they might be more relaxed on that rule. Not sure

Wiring for speedo attached. Looks like you can use the factory plug. KW wiring is such a mess though. Goes from trans harness to front chassis harness to emission harness to engine harness. Straight to the ecm in the most roundabout way possible. Pins 34 + 35 on the ecm.
Pins 17 and 18 are 1939 datalink.
Pete engine harness has the VSS plug right on it. Alot cleaner
Your engine is a 2250. Wiring diagrams are attached in the truck mechanic section.

Wow... appreciate the help. For me...that looks very overwhelming but I'll see if I can make myself understand. There's so much wiring on this truck compared to my 08 Western star. Lol Thanks again for the help
