What is it?

 

built in amp i do believe but i could be wrong

 

cruise control, but be more specific on what model your car is.

 

Doh! 84 GSL, I think the amps, 2 of them are bolted to the tin on the inside of the bin. This is a lonely box bolted to the pan of the car. :-)

 

yea it's your cruise control box, pull it out and no more cruise control.

 

That answers a question of mine that popped up as well
Thats good to know what that is. Now, if I wouldn't have opened those darn storage bins up, I wouldn't have found out about those two rust spots that are bringin' me down
