4-pin electronic relay for LED

OK, before lurch's post I ended up purchasing a CF-13 LED flasher which is a 3-pin relay (+ L -). When I connect the turn signal indicator switch (10 on the diagram) to the load it runs the relay constantly. I can't figure out why this is from the wiring diagram or what I can do to alleviate the problem. When both dash indicator switch and flasher switch are connected the relay just runs which would be annoying. At this point I could run the relay without the dash indicator but that isn't ideal. Perhaps I could bypass the dash indicator switch and wire directly to the dash indicator since there is only one indicator and not separate ones. Thoughts? I can try lurch's suggestion, but just don't want to keep buying relays.

Sorry, I was wrong. not 10 on the diagram pin 3 going to 7 on the diagram runs the relay when connected to Load.
