-Using a small screwdriver, or a pick, remove the plastic plug from the face of the 12-pin main harness connector. **Remove** the BROWN/Grey wire from Pin 2 location. This is a power wire, so be sure to tape it up & shrink-wrap it well to prevent it from shorting anywhere. Using the WHITE jumper wire that comes with the tuner, feed the open ended side through the rubber plug (into Pin 2 position) until it is flush with the face of the connector. Then snap the plug back into the face.+Using a small screwdriver, or a pick, remove the plastic plug from the face of the 12-pin main harness connector. **Remove** the BROWN/Gray wire from Pin 2 location.

 There is a 4 pin connector (SDLC Serial Data Link Connector) to the left of the battery under the battery cover. Pull it straight up and unplug the weather pack cap. On the back there is a white plug in the 4th hole (Pin 1). Use a pair of pliers to remove it. There is a 4 pin connector (SDLC Serial Data Link Connector) to the left of the battery under the battery cover.

 I started up the logging software and used it to Clear Data Buffer from the communications drop down. Once this was done I opened the PC Link software. I opened Rico's map. And then from the communications menu I chose "Upload to EPROM". I did it twice to make sure everything was worked correctly. Afterwards I started it up. It worked great. I used the logging software to play with it in real time. I started up the logging software and used it to Clear Data Buffer from the communications drop down.
