reverse wire is to connect to a power wire that only turns on when you are in reverse, so it can tell the reverse camera to turn on if you have one, eg, the reverse tail lights power wire.
The speed wire is to connect to a speed sensor to help with navigation when your satnav signal is in and out - if you have one.
