If you would favor to keep all manufacturing facility chimes,dings,on star etc. Climate you need to buy the harness(around $100) which allows you to reuse the data bus systems.If you do not care about this stuff(like me,didn"t have actually on star anyway) then ns bought a $10 harness that is detailed for gm vehicles that the exact same year. The switch power for the manufacturing facility system comes through the data bus,so you need to run a switch power wire(I simply tapped right into the home window circuit with an "add a circuit" from the auto parts store.) if you have a factory amp then you will either need to bite the bullet and get the high-quality harness(possibly another, not sure) or do as someone currently mentioned and also spend a ton that time to bypass the factory amp.
