Also, invest in a decent ratchet crimper. Your hands will thank you.

This is the closest I've seen so far, but 6 pages and no one comes up with Label Maker? Nothing speeds up troubleshooting faster than knowing literally at a glance which speed controller does what, which power/PWM/CAN/sensor wire or pneumatic tube is connected where, and how old motors/batteries/etc are if labeled at acquisition. By far the most handy, versatile, and time saving troubleshooting tool you can get.
