toyota camry rear window antenna booster

Do the stock radios on 2009's non JBL Toyota Camry's have a connection for a antenna booster or signal amplifier? It appears on the back of the stock radio there are (2) antenna plugs, one is the normal size male plug the other just above it is a small diameter but similar style. I assume I need to hook up a wire from a non facorty HU such as a Pioneer aftermarket (Power Antenna blue wire) to a wire which will turn on the booster or electronics in the rear window pillars? Does anyone know anything about this? Thank you

I found out that the BLUE wire on the radio harness is the antenna power booster and must be connected to the BLUE power antenna wire on the aftermarket stereo which in turn powers the booster. This should clear up poor signal reception.
