Our system (like many newer vehicles) is a five wire system since we have separate tail and brake lights instead of simply making one bulb brighter for
brakes. You can tag the wires outside right behind the tailights. Or, inside the jack compartment on the driver's side and the jack compartlment on the passenger side.
RT Turn Signal Wire Color (only avail on the Passenger Side): Green/Blue
LF Turn Signal Wire Color (only avail on Driver's Side): Green/Blue
Parking/Running Light Wire Color: Green/Red
Brake Light Wire Color: Green

I usually mount the converter on the driver's side and run the long green wire on the converter over to the passenger side light harness. Be sure to firmly ground the White wire on the converter - I include a self tapping screw and star washer - scrape the paint off of the body where you attach it or secure it under an existing stud or bolt that has been scraped.
