Relay 09 will run the fan at medium speed. Relay 13 will run the fan at high speed. (I think I also had to jumper relay 03, speed control.) I learned that, for the ECU control the fan, low speed requires relays 12 (cooling fan) and 10, and high speed requires relays 12, 03 (speed control), and 13. So, if relay 12 fails, no low OR high speed.
