Report: Wasn't so hard. Took me about an hour and a half. Had to take the bumper off. I used the "original" locations for hassle free installation. The factory horns come with one terminal, and no extra wiring was needed.
The bumper is held with mostly push pins. although I needed ratchet sockets. 10mm, 12mm and 14mm - so get your metric set (in case you only have SAE).
yup I told you its not a big deal to remove the bumper. good job sir.
