Familiar with pipe internals?

I have gutted an e-pipe in a quest to have all my devices use the same batteries. There are 4 wires coming off the battery casing to the atomizer, 2 red and 2 blue. Does anyone know if 2 are for the switch and 2 for power. I haven't had a chance to prod them with a multimeter yet.

Never mind. If anyone is interested the 2 blue are switch wires and the 2 red are the power output. Touch the blues and the reds output, you do have to figure out which is pos and which is neg.
