I have a question for the more electronically inclined. What gauge wire would you suggest to run for this thing? I'm guessing I'll need about 6ft of wire and it'll need to handle 20A. I was originally thinking of using 10ga, but now I'm starting to think that that may be a bit much. What do you guys think? Please explain why. I've used the link below in the past and its a bit confusing as it has a rating for chassis wiring and another one for power transmission.
