Rep Power: 389 The CF trunk should have nothing to do with your trunk light. Did you replace the bulb?

Rep Power: 429 you possibly have a faulty trunk light assembly. If you have a multimeter, remove the 2P connecter from the trunk light and check for continuity between the 2 terminals. If there is continuity, and the bulb is ok, you need to replace the trunk light (not the bulb).

A quick and simple test would be, with the trunk open use a short section of wire 5-7 feet long. Touch or attach 1 end to the METAL PART of the trunk latch assembly and bring the other end of the wire to a known good ground. If you light comes on you need to provide a ground path for the circuit.

Rep Power: 429 Ok, I guess I didnt read carefully. If you did plug the third brake light socket into the trunk light and it came on, then the trunk light assembly is working.
Now craig, the trunk has nothing to do with the ground for the latch. All the lights in the trunk, the taillights, turn signals, thrid brake light, etc... all use the same ground. And the trunk latch uses that ground as well. So if those other lights work, you know the integrity of the ground is good. There may be an open in the ground wire to the latch before any splices, but the circuit is already properly gounded. I think the problem is in the latch switch itself. Now he can check the continuity of the latch itself with the trunk open and closed, and he can also check at the connecter at the fuse box to see if the ground is indeed the problem or if the latch is also faulty.

Now there is some connecters at the dash fuse box you can back probe and check for voltage from the trunk latch. there is an 18P connecter under there with a red wire on the 18th pin you can check. With the trunk lid open, there should be 1 volt or less. With it closed, there should be 5V or more. If either are incorrect, you possibly have a short to ground, open in the wires, a faulty trunk latch, or a poor ground.
