How do figure out what spark plug wire goes where.

Everything I read said 'Don't mix the wires up.' I mixed the wires up. How can I get this truck running?

I have a 88' GMC S15 6CYL truck. I was replacing the spark plug wires and got them out of order while removing the old ones. Now, I'm not sure what to do. The repair manual says the firing order is: 1-2-3-4-5-6. It even has a diagram of the distributor cap and the cylinders, but the distributor cap in the digram only has six points. Mine has seven, one extra in the middle. I think the seventh point in the middle is the one that gos to the ignition coil, I'm not sure. Does anybody know, or know how I can find out?
It seems like it should, but I think I remember the center wire going to point #1. I wish I had taken a picture.
