Three way switch wiring

In my TT I just got, the front pass through cargo bay does not have lights in it. I have purchased some LED light strips that should work great. What I can't find is a simple 3 way wiring diagram for 12 Volts using common switches. I want a switch on each side of the compartment. Anyone got a nice diagram that I can wire up this weekend?

You need 2 SPDT switches, which is what household 3 ways are. Positive goes to the center of first one. Then the 2 outer connectors on the switches are tied together. Then the center of the 2nd goes to the light.

What I would do, get 2 NC magnetic alarm switches. Most I see that are NC have 3 terminals so you can use it NO, too. Anyways, I would put the mag switches on the doors and when you open the door, the light comes on.
