[V8] Rear Bulb out Warning

I did it on the cq.  I know it is slightly different then the V8q, but not
by much (I now have to do it to the V8q too, since I put LED bulbs in).  I
did look at the wiring diagrams between the two.  From what I can tell the
only difference between the two is that the V8q monitors the third brake
light and the the CQ does not.  On the cq, I solved the problem by grounding
the "red" wire.  I think it was labeled 22K.  I will look that up to confirm
if anyone wants me to.  I am sorry, I can't remember how I determined it was
this wire.  But, I do know it was logical based on the diagram.  I hope this
helps.  Oh, if memory serves, I think the control unit for the rear brake
lights is on the drivers side next to the antenna in the trunk (if your car
has the antenna).
