We think that is just a wire with a terminator resistor on it that is loose. If there are open pins on this set up, then check the terminal block which should be a black four plug junction block which may have a wire loose there. There are a couple, 3 actually, of different systems in 2006, and we would have to see it to determine if this is a terminator on the end of system link harness, or if it is an open harness for adding a link gauge. We will have to visit with those systems tomorrow and jog our memory.BCB
