Hi guys h0ws it going. I am hooking up a eletric fan harness iam having no troubles at all but i have a question. I am giving power to the fan from one wire from the harness hooked up to a male and pluging it in the spot that has 2 red (power wires coming out the fan.) and another plug going into the 2 black (ground) and then gounding it is it safe to use some of the left over power wire i didnt use for the ground?
