Pigtail - Metra 40-CR10
Wire harness - Scosche CR02B
You'll also need an RCA to bare wire adapter as the RCA plugs on the OEM-2 are on the output side of the unit. I bought a cable and cut it.

I tucked the OEM-2 into the cavity on the right wires from the emepg were tucked below the unit and the tuner module up and back in the cavity on the left. It took some packing to get it all in there but it's possible.

I think I'll go look for the Metra faceplate today... Mine is an American International. Got all three parts from Best Buy, I don't know why they don't carry all Metra or Scosche, etc...

Oh yeah I used the wires with red stripes for inputs (low power) on the OEM-2, There are two input wiring options high power or low power, 20 watts and above or below 20 watts. from the HU.
