You can just modify your harness for a multi gauge style by moving prongs around in the connector, here's a link I used to convert mine. http://gmcpauls.com/Tech%2520Tips1.htm. Pretty straight forward.

You can do as stated but the sendor units on the motor have to be swaped out as well for the gauges to read correctly.
