I have done this

and this one
This text is a slightly modified version of the procedure for the TC88 and V-Rod. I’ve added information to the items that I found confusing, in an attempt to clarify.
These steps MUST be done EXACTLY as written. Any deviation will result in an unsuccessful transfer of the password and you will need to start step 1.
1. Set Run switch to the Run position
2. Turn Ignition key On-Off-On-Off-On-Off-On (this should be done fairly rapidly, no need to wait for the engine light to go off. . . )
3. Toggle the Left Turn Signal Button twice. (This means PRESS THE BUTTON twice, NOT turn the signal ON AND OFF Twice, which would be four presses.)
4. Turn Ignition key Off-On quickly. Verify the Check Engine lamp illuminates briefly and then turns off.
5. Attempt normal start ONE TIME. (This means ONE press of the start button!) Engine starts and stalls immediately. Check to verify that the engine lamp stays on. Password has not been learned.
6. ECM enters Password Learning mode for 10 minutes. DO NOT cycle the ignition or disrupt power for the entire 10 minute cycle.
7. Quickly (within 2 seconds) turn Ignition key OFF-ON.
8. ECM enters Password Learning mode for 10 minutes. DO NOT cycle the ignition or disrupt power for the entire 10 minute cycle.
9. Quickly (within 2 seconds) turn Ignition key OFF-ON.
10. ECM enters Password Learning mode for 10 minutes. DO NOT cycle the ignition or disrupt power for the entire 10 minute cycle.
11. Quickly (within 2 seconds) turn Ignition key OFF-ON. Wait approximately 1 Minute.
12. Turn Ignition switch OFF. Wait at least 15 seconds. Turn Ignition switch ON and start engine to confirm the Password Learn Procedure is successful. Engine will start and remain running. If engine immediately stalls and fails to restart, the procedure was not successful. Start over at step 1.
The other thing that SEEMED to be happening was funny oil pressure light behavior, like not lighting when the ignition is turned on!!! Related? Who knows??? Here is what I do know, after running the above procedure three times, turning on the ignition lit the oil pressure light for the first time in 3 tries and the bike fired instantly. I’ll assume I did something wrong in the first two attempts.
