I've got 3 bikes to wire up dynamos and lights. I've found recommendations to use 22 awg wire but haven't found a source for buying a small roll of the "right stuff" Any Ideas?

I've used whatever was handy, usually 18 gauge. I seem to recall a doorbell taking 22 gauge, so maybe Lowes or Home Depot?

I bought wire at the hardware store. You want multi-strand, not solid. I think something like 22 would be better than 18 gauge, but I might have used 18. I twist the two pieces together and zip tie it onto the fork. I have used yellow and black wire, one of the bikes was yellow and the hardware store had that. I think on one occasion I ordered some wire on Ebay.

Initially I had three forks for one dynohub wheel, for a number of years moved that one wheel to where it was needed. That is why I zip tied wires to the fork blades on all three forks. SP and Shimano connectors that connect the wire to the hub are interchangeable, I bought spare Shimano connectors and use them on an SP hub.

If you are trying to connect a taillight, that usually uses 2.8mm spade connectors. I think Peter White sells them, not sure who else in USA sells them. I bought a bunch on Ebay, shipped from China, shipping often takes over a month. Some of the lights, for example the Luxos U does not have wires coming out of the light, instead you plug the 2.8mm spade connectors into the light.

Or, you could just buy a bunch of extra wire from a dynohub dealer or from Peter White. If you are also wiring in taillights, I think buying the real thing (the B&M taillight wire) from a dealer or from Peter might be worth doing, as that is a lot of wire. I am using hardware store wire on all my bikes from the hub to fork crown, but on bikes with a taillight, I am using the B&M wiring on all but one bike.

Some lights are grounded to the frame, some are not. You did not say which hub you have, Shimano hubs are also grounded to the frame. If you have a Shimano hub and one of the lights that is grounded to the frame, there is a 50/50 chance you will get it wrong, if you lights do not work switch the wires.

Good luck.

Amazon has a couple candidates. I have enough of the connectors but right now have a bike held up because I need a longer internal routed wire that passes through the bottom bracket shell.

I get all of my lighting stuff from one of the german online retailers. Here's an example. I combine it with some other german stuff to offset the shipping and make the order worthwhile.

3 bikes? Hmm.... how much wire will that be? Figure roughly 2 feet from hub dynamo to headlight, and maybe 3 feet (or more) to the taillight?
That's 5 feet per bike of twin conductor wire, so 15 feet for the three bikes.
For a single conductor wire, you'd need to use twice that much, and then twist the wires.

My preferred wire doesn't come in that small of lengths, but maybe it might be of interest.
It's some wire from Alpha, and it's similar to teflon insulation, but cheaper. Teflon is nice because it isn't as bulky as the more common PVC stuff. It's also pretty tough, mostly. The small size makes it more flexible, easier to route through small spaces, and perhaps doesn't stand out visually as much.
The Alpha wire can be found at Digikey...

but they only sell a minimum of 100 feet on a spool. $56 per spool.
Not cheap unless that's what you prefer and expect to use a lot of it.
