According to the FSM, there is a white wire that should power the horn and brake light circuits. It originates from the fusible link at the battery and splits off. One branch goes to the voltage regulator, one goes to the ammeter, and the third goes to the fusebox.. There should be two white/red wires, one coming from the alternator, and the other coming from the ammeter. The other power wires for the fuse box are blue/red and black/white.

Since there are 3 white wires in your photo, it's difficult for me to say with 100 percent certainty that it is for the horn and brake lights.

Here's my side-by-side pic of my old fuse box next to the MSA long-tail replacement.  As best as I can make out, the label on the white wire with the male bullet connector reads "horn".

If you unplugged it in order to plug the MSA fuse box in then there should be a female socket to receive the male plug white wire. It goes to the horn and stop lights.
