Jerod, I used 6 conductor, 14g trailer cord which is about 1/2" diameter. It is very well insulated wire and I would recommend that you use trailer cord if you are routing the wire along the frame. I am sure that 6 conductor, 16g would be adequate as I don't think the current draw is more than a few amps when the motor is locking or unlocking.
The 80 circuit is 30A to the ECU and the single locker ECU circuit is 20A IIRC. The 10A circuit that you mention isn't really feeding the locker switch. It is the power to the instrument panel. The locker switch just makes a ground on that circuit which turns on the light. Of course it will see whatever the current draw of the bulb is.
That was a long way of saying, yes, 20A is fine and 10A for everything is probably OK as well.
