I was thinking the rear lighted T would be simply pulling off the existing emblem drilling a hole for the wires fro the new lighted T (sealing it with silicon or something), re attaching it all, and then fish the wires down to the license plate lights and tap into that power source....
Fishing the wire would be a real challenge through the small hole and spaces. Conceptually it sounds easy. In reality it's very hard. But there's a part that runs the length of the rear appliqué and holds the two license plate lamp assemblies. If that can be removed easily we have a much simpler solution and probably the room for the additional electronics we'll need for the light to brighten when the brakes are applied. I'm going to check that ASAP.
