What gauge wire are the methanol kits running (about)?

 

Are you talking about for power and ground wires? If so , I would think a 16gauge wire would be fine. I can't imagine those units draw to much power, but if you are worried about the draw you could always run 12 gauge, anything over that would proably be overkill.

 

20-22gauge too small? ... i think you are right with 16 gauge though.

 

If you can find out the current draw on it or them, I can better tell you. 20-22 gauge might be okay, but will need to see the current draw.
