Speedo and gauges after swap

[Utfireman]

My wife bought me a truck that just had the Cummins/nv5600/205 swap. The speedo and I believe most of the gauges aren’t working. Is there a harness to adapt everything over? For those that did the swap, how did you connect the gauges, and also can you show me how the 4wd shifter was installed?

I’m in deployment for a few more months and trying to plan my game plan for finishing this truck when I get home.

You can use a 89-91 K5 or Suburban Speedometer with the electric VSS for your speed.

Everything else should just tie into the appropriate sender.

Not a truck my 89 C&C had a cable.

I may be off on the years, I always see people specifically call out the 91, but I'm pretty sure they got VSS before that.

You gotta have the correct DRAC module to transduce the sensor signal for the gauge, right?

Depends on the output.
