Got a wrecked truck listed above 3500hd 4x4 with the 6.6L diesel. Need the pin out diagrams for the C1 connector in the bottom of the under hood fuse block. Anything that has to do with turn signals. Somebody cut and put wires in the wrong slots!

Hello, are you referring to the X1 connector in the under hood fuse box? This is a diagram of the connectors for the under-hood fuse box.

These are X5-X8. Do you need the fuse box labels as well?
