I went the route of purchasing the harness, (about $70), and installing it a couple of weeks ago. I don't know the service department of my dealer, since I've never used them. I do work with a few guys that have used them, and didn't have good experiences. That was enough to make me just order the harness myself. I enjoy working on and "getting to know" my bike anyway. I had a good time relaxing in the garage with a cup of coffee, listening to some music, and switching out the harness. I paid for the harness, but it was worth a relaxing morning in the garage, vs an appointment with the dealer that may or may not have irritated me.
Funny, but along with the harness, I ordered the clip, just in case I broke it. The old clip didn't break, so I didn't need to replace it. Good thing, because the new clip disappeared somewhere in its journey to my door. (Cheap Cycle Parts sent the harness and clip separately). It's been weeks now, and I often wonder what happened to my little black clip.
