Review on Innovative Metra 70-1786 Radio Wiring Harness for Mercedes 94-04/Landrover 99-04 - Simplify Your Vehicle's Audio System Installation by Douglas Norton

The biggest plus of this product is the fact that I didn't have to cut any of the OM cables. Of course there was the fact that I had to remove the RCA cables and wires. Speakers straight into the aftermarket stereo wiring harness (not really a big deal, the bottom of the RCA cables are color coded wires like green/black, white/black, purple/black, so a solid color is positive, and black wires - negative ) * PS for those who have 3 port audio system in w124s, TOP PORT IS LEFT. He is hidden. The only plug you need to worry about is the double plug*
