Hi Karthik,
I want to confirm that it is permitted to use heat shrink tubing “for the purposes of protection, organization, or management”.
Also, can the permitted items additionally protect or organize the plugs on the wires?
Lastly, how come they can’t be used for 4 wire extensions?
Thanks!
This question will be answered after the scheduled June 2nd manual update. We appreciate your patience.
No rush, Karthik! I probably wouldn’t get to wiring anyways until 2 am the day of the competition. 
I really hope we’ll be allowed to do this, as it will be really helpful with wire and connector management.
Yes, this is legal.
Yes, this is legal.
This was an oversight. They are legal now. Please see the following Q&A entry for more details.
