Location of Headrest speaker plug in
 

I have searched threads in archives, audio, specific ones, but to no avail. I have located the male end of the plug from floorboard, but cant locate the female end on the seats. Can pull one out if necessary, but thought someone might have idea as to location. Car FC3C 1990 Vert. Thanks.

It should come out the bottom of the seat near where the other plug is on the floor
