Nah, look again, closely. The green wire connecting screw has a "+" sign built in, obviously the positive connection. The red wire connecting screw has a "-" sign built in, obviously the negative connection.The right red wire is the +12 volt.
The left green wire is the ground.
Oh, I get it, the large red wire is bipolar
Aha! The green wire is connected to the positive screw and the red wire to the negative screw. Either this is a negative supply or,,, Benjamin Franklin was right, Electricity does flow from positive to negative. I'll go with Ben. After all, he did write articles under the name Silence Dogood.Nah, look again, closely. The green wire connecting screw has a "+" sign built in, obviously the positive connection. The red wire connecting screw has a "-" sign built in, obviously the negative connection.

Well I found this on the internet so it has to be true. But to maintain peace and not get into a war of words with you,
I'll let an electrical engineer answer this, Jim Dawson settle the argument 
I think when the electrons flow past the screw threads it will create a negative energy vortex and possibly affect the space time continuum. This is most likely to occur at 88 MPH.Well I found this on the internet so it has to be true. But to maintain peace and not get into a war of words with you,
