If your antennas are part of the rear quarter window glass on each side of the Runner ( that is a line inside the glass) and you have an aftermarket stereo you would only be able to plug in one antenna. In other words the original stereo had 2 antenna plugs in the rear. One large and one small.jamr1 said:The clock was pluged into a dumby plug on the back of the trim piece??? Plug fit perfectly, but no mail parts in the hole. I guess this was done when the stereo was put in. There is a loose wire behind the stereo, it looks like an antenna insert for the back of a car stereo, only a little smaller? Is this the part from the antenna that plugs into the factory stereo??
