Ditto, did the same on mine. $17 harness, the only PITA was the colors were off, so had to do some testing with a 9v batt...took about an hour to install..
Runing an after market deck with an amp and 2 subs, stock fronts.. 3 years and no problems..
As to your other post about 2 harnesses. You need your BMW one, once unhooked from stock deck it's the female end, so you need a new one to plug into that one(male) with the wires hanging loose, take those loose wires and connect them to your loose wires from your deck's harness.
