Answers :

Begin at both ends...work towards the middle. What I mean by this is first, you changed the fuse...was it blown? is there power at both fuse ends and past the fuse?
Is there power at the bulb contacts in the sockets at the rear? are the sockets properly grounded? Is there power at the lead coming out of the light switch that supplies the tail lights? Are there any connectors underneath the vehicle and are they in good condition and have power?
You can use a basic test light to do the testing but I suggest you use a volt meter, as it not only tells you that power is there but how much as well. One good thing about working on that vehicle is that there are no "magic modules" in the system and wiring goes where it's supposed to, without any "side trips". Therefore tracing it out is fairly simple. Since there are no computer issues to worry about, often you can run a new wire from the last place you find power (providing the switch is working) right to the light harness in the rear, as long as you cap off the original wire so you don't make a potential place for a short to happen.
