Sorry about that. I deleted that as I read your problem.
The system is probably reporting an error has been detected with the left side handlebar module.
There is only 4 wires to it and maybe you damaged one or pulled the connector out.
Do you have a tuner device that can read DTCs?

All I can suggest is you open the controls at the handle bars and using an ohmmeter check continuity and also if any wire connects to another or to the bars to that connector at the other end.
Disconnect maxi fuse as they are always powered on. Maybe you didn't know that and maybe you damaged the electronic module in the handlebar.

Multi meter set to ohms reading. Connect leads together and see 0 ohms.
At the connector see a black wire. Connect one lead there. At the handlebar control connect other lead to black wire here. See 0 ohms. Now see other wires. Connect ohmmeter lead to each one in turn. It might be a resistance but it shouldn't be 0.
At connector connect to another wire and test at handlebar as above.
If wire to wire of same colour you don't get 0 ohms then you have a broken wire. If you have 0 between 2 wires then you have a short.

On the CAN bus bikes there is the maxi fuse and only one other fuse. As the right hand controls are working the system is working in general. The BCM has electronics that does the job of fuses.
In the connectors is a pin pushed back or bent or broken?

Link in my signature takes you to HD serviceinfo portal. Enter VIN and then search available documents for wiring diagram.
One connector has visible pins the other will have the sockets. If the sockets are on the connector to the hand controls then you will need something like a pin to go in the socket to test.
