Yet another 15 amp fuse thread

I'm finally down to figuring out my blown fuse problem. I have disconnected the alarm plug under the top box but haven't jumpered anything and the fuse still blows.
So that leaves the horn and/or the brake lights. Right?
Are there some easily found connectors to undo to check either?

Re: Yet another 15 amp fuse thread

take the RH foot plate off and make sure the switch wire hasn't been trapped

Re: Yet another 15 amp fuse thread

Did you undo the three pin connector (circled in blue in both pics) with the red wire? That is the one that is blowing the fuse F4.

If you have not then undo it and if the fuse no longer blows then re connect it and CUT the red wire. You may not need to do any jumping if you leave switched power applied.

That was the one. The Wrencher Extraodinaire comes through once again.
Connector pulled and the fuse did not blow. Cut the wire then I reconnected everything I had disconnected.
I now have a working horn and brake lights.
