I'm in the process of putting a Kwik wire harness in my truck. It's been converted to 12v. The four wires coming off the switch are 11, 11, 27 and 12. 27 would be keyed power, 12 goes to the ballast & coil, and the 11 and 11 get power off of the alternator wire splice. My question is do I need to splice both 11s together or could I use one and cap off the other?
