Easiest and about the only way is to find a WIRING DIAGRAM for your GMC year and cut each wire from the pin terminal and slice to the new harness wire that corresponds to the pin output. Since you are replacing your gauges you probably won't be using the idiot lights on your dash - plus you will need to switch sending units - you can do this just think out the process and plan before you cut.
