what i'm doing is adding the bose headunit from a 2k3 to my non bose 2k... i already have aftermarket speakers and amp...so i took my stock headunit out and i saw that the this is how the install was done....there are 4 plugs on the back of my headunit.... only 2 plugs are used and 1 of them is the black cable....and the other one is the big plug.....i think i saw a line inverter and a y splitter... i noticed on the 2k3 bose hu, 3 out of 4 plugs are the same as my 2k hu...so do i need the AOEM-NIS2 pac? any help would appreciate it....

 

any help anyone?
