Hello. Thank you in advance for any help. I've already checked all threads on the subject matter and posed this same question elsewhere, but it has gone unanswered for a while and I'm wondering if it's because it hasn't reached enough people. If I'm wrong, please forgive any breach in proper posting. Thanks to the advise received in that other post, I've found that the way to go when replacing the horn in a 2016 453 model is definitely through the driver side front wheel well. Once the wheel and the inner well cover are removed (no need to remove the whole well cover, just the front half screws and it can be easily folded out of the way), access to the horn is fairly easy. Yet, the first problem I encountered was that the factory plug has both wires connected into it and the plug does not fit into the connector on the replacement horn (Bolo Bad Boy.) Therefore, I had no choice but to cut the wires and install them separately. However, no matter where I connected each wire, the sound of the horn was not as loud as shown in videos. Somewhere else in that thread I read that it is not necessary to instal the square fuse that comes with the replacement horn. However, could this be the reason for the poor sound I get? Also, should I need to install the fuse, how do I install that big square fuse in the fuse box? It has four different prongs and I'm not quite sure how or where it would fit. I've found two separate fuse boxes, one under the hood and the other behind the glove compartment, yet I cannot find a way of fitting the square fuse that the replacement horn comes with anywhere therein, should it actually be necessary to install it. Am I missing another fuse box? Any advise will be appreciated. Thank you.
