I had a switch or relay blow in my car when someone was working on it and they used a blade fuse temporarily so i could get my car home. I now need to replace this fuse. I lost my owners manual so i duno what the relay/switch runs. It is the top two one is a 60 amp and the other calls for a 20 amp. It is shaped like a little box with the top being plastic transparant. Can anyone help me w/a part number. It pretty much controls the whole car. Car wont run without it.
