Adding horn without removing OEM horn?

[Ramster96]

Is there a place on a horn relay terminal that I can catch the hot wire and just run it to a new horn without trying to search out and find the old horn? I know my relay works because I can hear it click when I hit the horn but I can't find the old horn??? I have a 96 1500 Ram Thanx!!

the horns should be on the passenger inner fender under hood up near radiator.
I do not know where to place on relay, other than trial and error.
