I'm wiring my new pickups for 18v. The second battery plug i bought i noticed later has thiner wires then the battery plug that came with the pick up. I was wondering if thats ok or could it be too thin to carry the 18v or what ever goes through em. I dont really know thats why im asking. Im talking about the second 9v battery plug i bought that goes in between the first batttery and the pickups.
