Just did your mod..HATED looking to see that the lights flashed on arming! Installed the 065 p/n and thought "no way".. went and bought the 95 decible. Guess what, polarity does matter! It's all good though. 12 bucks later I chirp, and actually like the louder tone. Another 2 cents worth, there is a screw above the fuse box that holds the rubber seal in place for the hood. Back it out about 1 turn, place module on bottom side and tighten screw. Figure facing down will help prevent any moisture problems.
