There are three #14 wires with plastic connectors, one from the horn button, one from the key minder/door switches and one to the horns, that are keyed for the correct location. The other heavier gauge wires (#10) connect to either of the two screw terminals. There could also be other lighter gauge (#14) wires for options like under hood light etc. or aftermarket add-ons that also connect to the screw lugs. Both screw lugs are at the same electrical potential so it doesn’t matter what lands where.
