Re: 1991 electric suburban gauges into a square ls swap
The 91 guage cluster pinout diagram is on here somewhere if you search for it. On my 86, there were only 4 or 5 wires that needed to be swapped around in the plug. A very small flat head screwdriver is all you need to remove the connectors from the plug.

Re: 1991 electric suburban gauges into a square ls swap
I know ive been going to the pick and pull every sunday for the past 1 and a half months to see if i could a set because everytime i went they where always gone . Plus i wanted to maintain the factory look and also didnt want to drop a crazy amount on gauges
Ill try and look for another set next time i go and try to see if anyone on here needs them.

Re: 1991 electric suburban gauges into a square ls swap
Just to clarify, only the 90-91 K-5's, Suburbans, and R/V trucks got the electronic speedo. My 89 K-5 was an oddball year because they came with the newer NP241C but still ran a cable speedo so I wound up having to pull the gauge cluster from a 90 Suburban for my swap.
