metra wire harness for hummer h3 without the chimes??

does the h3 require the GMOS-04 harness? ($99 harness) if so, you can purchase a 70-2003 instead. You will lose door chimes, onstar, and any seperate info display you might have. Also, you will also have to find your own accessory power with this harness.

 
cool i think thats what i need, a local shop wants 25bucks and bestbuy wanted 99 for this simlar harrness. lol shit i never pay retail
