Guys I see the service manuals on here. I can't find anything for my 2000 k2500. The wire colors seem to be different than other years. Wanting the diagram for the steering column.
I'm also driving a carryover GMT400 ('99 C2500) and I found these manuals in reply
#77 of that thread.
These carryover models (that were aimed primarily at commercial/fleet customers) were pretty much frozen
design-wise at this time, so the '99 GMT400 Manuals should be a decent resource for what you are trying to do.
FWIW I actually recommended this same solution to an earlier question on the missing '00 manuals, and the member
replied back afterwards that the wiring colors *did* match up for him.
Give the '99 manuals a go & see if they will work for you.
Best of luck --
