O.K. Thanks for the help. I've downloaded an printed out the reference material.
Located the test connectors. There is one set of male-female single pin connectors that are green, another that is white. I do not know which is the "Read Memory" and which is the "Test Mode" connector. Manual (Chilton) doesn't say. There is also a black 6 pin female connector, and a white 4 pin connector, which I guess are for scan tools...
Spent most of the day at machine shops getting bearings pressed into various bits of my motorcycle, came home and cleaned the Soob engine, and installed a 195 degree thermostat where none had been before. This caused a change in the sound the engine made, and resurrected the temp indicator that I'd thought dead. The check engine light came on, stayed on for about half hour, finally went out, hasn't come on since.
I know that the temp indicator is separate from the engine temp sensor, guessing that the ECU is distressed by engine running too cold.
Tomorrow, will start pulling codes, if you can tell me which test connector is which...
TIA
