Anyone have a diagram of what the wires in the huge harness that connects cabs wires to engine and components? I swapped a 01 cab onto a 99 tram tyranny and engine and having a few electricals not matching up in there and need to do some splicing

 

Might want to look at the wiring diagrams in the '99 FSM that you can download from the FAQ/DIY section and see what you can figure out.

 

Thanks!

 

And for a cross reference, you could use the parts manual. It has abit on wiring too.
