If you know what these two parts are please post. I am having trouble with wiring issues and need help. Thank you.
I am trying to find out what the "white square box" is & what the "black oblong rectangular box" is. This is on a 1990 RS Camaro. The location is under the dash, right next to the center console on the driver side. The silver round thing is my flasher/hazard sender if I remember rightly. (Which I don't always do).

 

The white square box looks like a relay associated with an accessory of some kind that my car hasn't got (I have no such relay) and the black oblong box is the chime unit that makes noises if you leave the key in the ign or the lights on when leaving the car . That little sub panel is called the "convenience center" by GM , even though it ain't really all that convenient to get to !

 

I'm sorry about the "late" thank you-Thank you.

 

The white box is the horn relay. It is aftermarket, I have one.

My chime box is blue, but I guess they could be black also.

 

Thank you too. In looking back at my post to try to help identify the newest "what's that part" for someone else I noticed your helpful post.
