The OBD2 Wire

The next thing we want to do is to prepare the OBD2 wire using the butt connectors. The first thing I did, was cut down the cable from its original size, to roughly 1.5-2ft. This way I dont have a massive slack of cable to carry around. Second, I snipped off all wires that I didn't need, and only left the 4 that I had mentioned.

Once you have snipped and trimmed the wires, you want to attach a telephone butt connector to the red, purple and orange connectors. Make sure you crimp these down nice and tight.

Telephone Gauge Butt Connectors

Once you have done this, you need to grab one of your 18 gauge connectors, and test fit one of the ends to the 1W location on the back of your radio. The reason you need to do this is because the pin is actually a wider pin and not a round standard pin. I had to take the end of the connector and flatten it a bit so it would slide onto the pin. Once you have done this, crimp the other end to the black wire.
