The harness itself connects quickly and securely, kinda bulky but they were only working with what bmw gave them. The quality of the Amp integration wiring shows in the sturdy fabrication. Overall pleased with the harness not the factory amp.
What's great about it: Factory Amp integration saves having to rewire entire system.
What's not so great: Limited by power output of stereo, weak pre-amps = extremely weak factory amplification.
