[69gmcshorty]

ok, so modification is neccesary. now that im thinking of it the p/o did a horrible job of installing a painless wiring harness in the truck. I cant find a model number on the harness and my next question is, is there something that i can see to tell if the new harness is setup for the gauge type dash or is it still the dummy light setup? i only have one connector in the back of the cluster so i am unsure.
thanks for all the help, Tyler
