-On the 04 Sportster, disconnect the 12-pin connector that plugs into the stock ignition module (under the seat). Remove the two bolts holding the module in place and replace it with the TC88A unit.
+**NOTE:** Always remove the Maxi-Fuse while working on the electrical system of the bike to prevent unexpected shorts!
-Using a small screwdriver, or a pick, remove the plastic plug from the face of the 12-pin 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.

 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.

 I plugged the Deutsch connector of the USB cable into the 4-pin SDLC and the USB end into the connector of the laptop so I could get started.
+Before programming the unit, Rico suggested to first set the knobs to 5 and 5 for initial timing & slope - then set the rev limit to what I wanted. I chose 6,000 (the knobs will control the rpm limit if you do not program a 'fixedlimit').

 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 was in the process of installing a mini tach as well. I learned that you needed to use the PC Link software to download the EPROM. Then in the edit menu you can set the Tach signal to on. Then you can reload the map to set the flag. I turned the bike off, and back on to reload the new map and settings.

 You will need the TC88A unit and the USB Interface USB-INTF (P/N 18014 from Daytona Twin Tec). Set the switch on the USB-INTF to 'TC88A and All Others'.\\

 You will need a power pack that is rated at 12v, 300ma, or better. Pay for a decent quality power pack. It is important to have a clean 12v power source with low-ripple. You will also need to create a small harness to connect the TC88A to the USB Interface and to the 12v Power Pack.
-You will need a 12-pin connector for the TC88A and a 4-pin connector for the USB Interface (this is like the SDLC from the bike).\\
