I have one installed currently (with a Kenwood KIV-701) and it works perfectly. I am going to be moving to aftermarket amplifiers soon (as well as replacing the door and rear speakers), so that I can have separate gain/crossover/frequency shaping control of the system components for overall optimization.

The nice thing about that harness is that that you can cut the rear RCAs which don't do any good and use them as the basis for the sub pre-out, like so. The best part is that they have already handled the tricky part of stripping and splicing the coax if you cut them off right at the block.
