I just bought an 88 rx7 and there is a *** on the right side of the cluster that in between the window wipers and hazard lights that looks like a rear window wiper control but i have no rear wipers. im guessin it was replaced from another car but just makin sure if rx7s have rear wipers at all.

Also my seat belt warning light does not turn off even when both are connected but the buzzer does stop. I wanna know if the passenger side ever affects the light before experimenting.
