Hello, I have 2 horns to remove/replace , they are behind the front grills . I have removed one of them off the bracket but the electrical connectors look quite corroded onto the horn connections, therefor making it difficult to remove them as it is not possible to see how they were connected originally. There does not appear to be a threaded small screw on top , I have pictures if anyone has any knowledge on this subject , thanks for reading. Brian.
