Charging issues?

OK, nevermind the yellow and purple field wires. I just realized the yellow wire is from my relay socket. This thing is making me stupid. I have a Ford solonoid up front to run the starter also the kill switch is a single pole. Does it matter witch field wire the relay is switching. I have it on the terminal closest to the bat stud. The relay is powered by a run source, I just can't remember where it comes from. I'll look tommorrow. Thanks for the help.
