Wiring guage and fuel sender conversion wiring

I have discovered I need to plan for 5 wires to run to the AP servos. Will 20 gauge suffice for all (run length should be about 15 feet)?

As a separate question, I have a Vision Microsystems probe running the full length of my wing. I know it will require a converter to work with the Dynon but I also have another small fuselage tank. I could live without a fuel quantity indication from this tank but would prefer to have it since the Dynon will indicate level in both tanks. I have no probe for the second tank although I have found one from another builder which is also VM. If I buy a converter from Princeton for each tank I think the Dynon will handle this fine. If, however I just buy a probe compatible with the Dynon (which I think Princeton also sells), can the Dynon read correctly with the different probes?

At that distance, 20 gauge should be fine if it's an SV32, and marginal if it's a SV42. Consult a wiring chart for the amperage of your servo and the wire run you're planning on.

As long as they output a variable DC voltage within 0-5V, they should work (this is what the Princetons put out). We don't have any experience with the VM + Princeton coverter though.
