Converters are sold at almost all auto parts stores and even in places like Walmart!
They convert five wire systems to four wire systems.
IE: coach--Left turn, right turn, brake, running, and ground--five wires.
Toad--Left turn/brake, right turn/brake, running, and ground--four wires.
The four wire systems use 1157 bulbs (or similar) with two filaments--one filament for running phase and one brighter filament for turn/brake. And then you need a wire for a common ground between the two vehicles.
The five wire/international lighting system uses separate bulbs for brake and separate bulbs for turn and separate bulbs for running. Hence the five wire system. One wire--left, one wire--right, one wire--brake, one wire--running, one wire--ground.
