I can give you a verbal but photos will have to wait until tomorrow-
Remove the seat, then the toolbox (four screws, it is very easy). The ECU (the ECU that you want to reflash) is behind the toolbox, just under the shelf at the back of the saddle compartment. Remove one battery terminal before pulling the ECU to cut power before unplugging the ECU. The ECU will pull pretty easily toward the front of the bike and there will be two electrical connectors that plug into the bike's wiring harness. There is nothing other than a form- fitted rubber strap holding the ECU in place.

I remember a good thread (with pics) about how to locate and remove the (correct) ECU. I'd like to send it in to Dynotronics for reflash and wish to do it quickly and easily. Does anybody have that post to share? TIA
