Like jwight said,Wolo's are plug-n-play.And LOAD!!!
Well, I installed the horn this morning - here are my observations:
1) I went with the "take off the body panels" process. It really isn't that bad; except, the next time I take off the side skirts, I'm just going to go buy 8 new plastic clips and be done with it.
I'll tip my hat to anyone who can install a horn on this car w/o taking the body panels off. I'm sure it can be done, but I would not have been able to fit by hands and arms in all the small areas.
2) On my 09 car, after the horn was installed, it stuck out just a bit too far, meaning the front panel had an extra 3/8" gap below the driver's side light lens. I didn't like this, so I bent the original horn bracket about 1.5" from the bottom at about a 60 degree angle. This allowed me to put the horn in sideways (when compared to the photogrpah above); allowing the front panel to fit properly and to have the "trumpet" orientated in the correct way according to the directions for the horn. Also, by orientating the horn the other direction, I wasn't stretching the original wiring harness as much, and, the wire's were not stuck between the hown and the frame - I was concerned this may be a rub point for the wires.
I'm quite happy I took off the frotn body panels. The process is quite simple, and now I'm confident I can change the color of my car relatively easily and not have to pay someone else to do it.
Thanks for all the advice!
I spent about three hours on the garage floor yesterday trying to get a Stebel Nautilus hooked up by going thru the fender well after removing the wheel. I managed to get the horn mounted, but it was about thirty degrees off vertical. Instructions say that it must be within fifteen degrees or you risk future failure. I fabricated an extension bracket that would have raised the horn higher and allowed a more vertical install . . . and then I dropped it somewhere into the depths of the front paneling while trying to install it. After probing around for half an hour with a magnetic pickup tool, I packed it in and reinstalled the original horn. After all the scrapes and dings my hands and arms endured, I'm convinced that the "best" way to install will be by pulling the panels off and mounting it on the passenger side where the second factory horn is meant to go. Now I just need to solicit some help from a neighbor to assist with that. . . wish me luck~!Congrats on the install. I spent a miserable 30 minutes last summer trying to install the horn through the wheels well - no go, although others have done it. Front panels coming off shortly to finish up the project.
You can also install the Wolo Bad Boy horn through the driver's side wheel well. If you turn the wheel all the way to the left, you can reach the 3 plastic fasteners that hold the liner in place. Remove them and you can bend the liner and slide in the new horn in through there. After you take off the factory horn, you connect the original wires to the new horn and mount the Wolo on the other side of the bracket (closer to the firewall). It's a tight space to work in, but I was able to do it in under an hour in 30 degree weather. (I mention the temp, just in case anyone was wondering about the flexibility of the wheel well plastic liner.) There are also good DIY threads on the SCOA forum.
We have just added the Original Italian Fiamm Horn (which we later discovered WOLO is copy of). The quality is a bit better, Fiamm is Italian and WOLO is Chinese.
The cost is almost the same, but the quality is a bit better. In case you are interested here is the direct product link:
