From the battery positive post you should have a red #10 wire that connects to a #14 fusible link then to a junction block next to the radiator. A second red #10 wore connects to the j-block and to the horn relay the alternator output (“One single wire on back”) also a red # 10 wire is spliced to this wire.
“Plug in of two on the side” One a white #16 connects the alternator R terminal to the voltage regulator#2 terminal the other a dark blue #16 wire connects the alternator F terminal to the voltage regulator F terminal.
