Relocating head unit & hvac controls

When relocating your head unit and hvac controls, do you have to extend each wire individually or can you buy some type of extra long wire harness extension?

I will be moving these two components from the dash to a center console in the near future.

As far as I know you just have to extend them yourself. Never seen anything that did that for you.

I've done this a couple of times and have used ribbon cable and just ran one single wire at a time...The one wire at a time is the best I've found,if you color code all the wires even better...Ribbon cable works good too and its flat,but a pain in the ass sometime to run around small areas...
