You're burning my brain

...been awhile since I looked at a gen1 (I have gen2).
Small light, bottom left(I think left), continueously flashing while the key is ON, bike doesn't have to be running but can be. There should be no lights lit on the guages with key on, bike running, so that's probably the one.
There is a white plug under the driver seat, it has a cap on it, nothing plugs into it from the bike. Use a piece of wire or paperclip to jump 2 of the wires, red/white and black/white(this is safe and will not harm anything) this is commonly called dealer mode. Again key must be on, and doesn't matter if bike is running. This will cause a code to appear in the lcd display on the dash, always the letter "C" followed by a 2 digit number. This is the trouble code, these can be referenced on this site also. If you have no problems you will get C00 displayed.
The picture shows the plug with the cap on, but it's just easier to remove it to access the pins.
