Question
I recently replaced the radio in my 1979 corvette since then the windshield washers and horn do not work there waqs an extra grey wire and an extra pink wire that I did not know where they went so I capped them I dont know where to look on the fuse panel it is not labled for these items

Answer
I am a Model A guy, not a vette guy.  Join a vette car club and ask them.  They will know and be happy to help you.  You might try to put voltage to the gray wire and see what happens.  Use an OHM meter to make sure it is not grounded before you touch a hot wire to it.  Same for the pink wire.  Should be easy to figure it out since they were both working earlier.  Get  a service manual for you car from chevy and it will show in there.
good luck.
