Is this the only harness I'll need?

I am gonna hook up my head unit in my 04 Monte Carlo pretty soon, I just need to get my install kit in (ordered today) and get the harnesses I need. I was told by a rep at PAC that all I'd need is the C2RGM24, however, she said that this is to use the factory amp. I don't want to use that because it's wired to run at 2ohms so I need to run my interior speakers off the head unit until my HiFonics amps arrive.

Anyone ever done an install on a late model Monte? Did the lady know what she was talking about and is there another harness I can get that will bypass the factory amp or does it need to be done manually? Anybody know how to do it manually?

Thanks in advance.

BTW, my system is non-bose, non-onstar, factory amplified double din am/fm cd player, no steering wheel controls.
