You can mount the coil in any orientation, so the best that can be said at the moment is, "One of the two side connections is positive, the other one is negative." You will have to look at the coil itself to see which is which. The terminals are labeled, and they are also numbered. I forget which number is positive and which is negative, but a short glance at the wiring diagram will tell you--look for the little numbers right by where the wire trace connects to the component.
