Campagnolo Cable Housing Question.
I am in the process of building up a new bike. It is 66cm so the stock Campagnolo Derailure housing for the shifters were a little to short. I ordered new casing, but I mistakenly ordered 5mm instead of 4mm. Is there any reason why the 5mm will not work? The shifters are Campy Centaur 10's. Thanks.

For Campagnolo, 5mm is brake cable housing; shift cable housing is 4.5mm.
If the housing you bought is brake housing, it will not be of the compressionless design (i.e., the steel strands that make up the housing are almost parallel to the length of the cable) and using it will adversely affect shifting performance. However, not all 5mm housing are brake housing so it is best to inspect.
Campagnolo does instruct to put ferrules at the Ergo end of the shifter housing, at least for their cables. So you may want to see if any 5mm ferrule will fit into the Ergo's shift cable hole.

I am curious to see how this works out as I would also like to use some 4mm housing with campy ergo shifters.

What year campy?
If the new 09 pointy things, the ergo levers are designed for their housing and their housing only.
If the second last generation Ergo, the housing really won't fit. 4mm is better. You can make it fit but it's not ideal.
I can't remember the first gen ergo.
Although late to pipe in on recommendations, I really like the Nokons. No compression, follows bends very easily (important for my 52cm frame, less so for your 66cm). There are other similar modular housings out there. By using add-on kits you can extend their length. Oh and I use the Nokons right up to my second-last gen Ergos.

Here's the facts. Pre-2009 shifters use ferrules at both ends of the shift cable housings, so it makes no difference what cable housing diameter is used, as long as properly fitting ferrules are used and the cable is compressionless shift cable and not brake cable.
For all 2009 ultrashift ergopower, either Campy's new 4.1mm cable housing or some other 4mm housing MUST be used, because no ferrules are used at the ergo body and holes are only large enough for the 4.1mm housing. Housings other than Campy's new ultra low friction may cause excessive friction and shifting problems from larger cogs to smaller ones.
I was forced to use some Jagwire 4mm cable housing for an early setup, when the seller shipped me a 10 speed cable set with 2009 ergopower. It did not work well due to the increased friction. I haven't had a need to try other brands, but I have purchased some Shimano 4mm housing that I will try at some point.
To avoid buying full Campy cables sets when all I need is the shift cable housings, I'm using the Campy cable housing only on the critical right side and saving the extra housing for later. That still leaves me short of housing for the loop at the RD, but I figured it was worth trying.
