Well, it wouldn't be a relay, just a solid-state flasher unit... I haven't installed one myself, no. What are you after here? If you want a quieter-sounding turn-signal flasher, take it out of its clip (on or near the steering column support brace) and let it dangle free by its wires; that will quiet its clicking a lot. You'll need to remove the lower hush panel below the steering column to get access.
If for some reason you're looking for a higher-capacity unit (e.g. for trailer towing), there are heavy-duty flasher units available from places like J.C. Whitney.
