buy a wiring harness for that year of truck, probably find one at any audio store for 15 bucks. Ready the wiring diagram and delete what you don''t need. i dont think it will be easy but it is possible.
It won't work. It has no acc. power wire. It gets it's acc. power through the data wire. Plus most of the newer GM radios have a new theftlock system built in that reads the VIN of the vehicle that is programmed into the computers. Trust me I do this for a living and I get so many people that come to my store and want me to put these units in for them. They are pretty unhappy to hear the bad news but there is nothing I can do for them.
