Is it working OK or, is just untidy? If you need to tidy the wiring up you can install a wiring terminal and where the wires come into the console you can connect them one at a time without any wiring knowledge.
For example: Disconnect the wire to the anchor light and attach it to the terminal, cutting it to the right length to keep it tidy. Then take a new wire from the switch to the terminal block keeping it nice and neat.
Continue until you have completed all the wires tidy them up with cable ties.
Job done.
