The bigger the better. If it will be the main power or ground, I'd go with 4 gauge or bigger. 2 gauge ought to be more than plenty.

You can get terminals with them.

I put the test bulb between Pos and Neg posts to make sure it lights, then between Neg post and Neg cable. No light. Does that mean there's no short or the moon's in the wrong phase? Maybe it's Obama's fault. I have a wing nut battery clamp on the Neg battery terminal and a side terminal post clamped in the Neg cable with a 4" piece of flattened copper pipe bolted to it and a hole drilled in the other end that connects to the wing nut post to make it easy to disconnect the battery. Sometimes when I reconnect the battery I get a spark. Other times not. When I disconnect the battery I attach a trickle charge unit on it so the battery stays fully charged. I suppose I could leave the trickle charger off for a week and see if the battery discharges even when not connected to anything. If I had heavier / stronger springs on the hood and could figure out how to put them on I probably wouldn't bother doing all this.
Thinking about going with 1AWG welding cable for the disconnect. Read it's good for 250 amps. Don't know the amp draw on starting or running. Only going 6' or less each way coming off the engine to the disconnect switch in the cab then back to the battery.
