Mixedbreed,
The correct harness for 99-00's is

The harness part numbers you listed are not correct. Ironically I actually purchased the harness you listed my first time around which prompted me to make this thread because again that harness IS NOT CORRECT!
The harness link above and the one listed in earlier posts is the one that I personally used along with two other 99-00 owners and it is absolutely the correct harness.
ANYONE WHO OWNS A 99-00'S REFER TO MY EARLIER POSTS IF YOU ARE LOOKING FOR A CORRECT INSTALL ON A 99-00 MUSTANG WITH THE MACH SYSTEM. THE INFORMATION LISTED IN MY TUTORIAL IS CORRECT AND DOCUMENTED WITH PICTURES AND VALIDATED BY NUMEROUS MEMBERS WHO HELPED ME MAKE THIS TUTORIAL!
Yes this is the same I harness that I personally used on my 2000 GT with mach460 and can verify that it worked. Now my friend here says he tried that 70-5521 harness and it DID NOT work on his 99-00, hence he came to me askin what I had used, and I refered him to the metra 70-5511, which is the one in the link he posted. WORKED LIKE A CHARM. Im sure all this harness confusion has to do with the subtle changes that were made to the mach460 in 01 model years, but the above link contains the correct/proven to work harness for the 99-00. Granted there are other variations out there, some with gain controls on the speakers output signal, which would probably be useful if one chooses to purchase a ****TY radio with an even ****TIER EQ, but I have no idea of these work on our 99-00 cars, or the 01-04 for that matter.
