They probably run the 3rd brake light off the stop light switch. The current from the stop light switch must also go through the turn switch to opperate the individual turn- stop lights. The turn switch must have 6 or 7 wires. If it only has 4 it will have to have separate rear lights but I dought if thats the case.
