How to Get Seperate Wiring on a Trailer From a Tow Vehicle with Combined Wiring

Question:

Dear Sirs Hopkins Towing Solutions tell me you might be able to help. Basically Im looking at converting a traditional combined stop/turn signal setup to a more modern separate stop/turn signal set up. Essentialy the opposite of this : http://www.bugmanweb.com/gsxr/gsxrimages/integrator/hoppy48845.jpg Do you have such a converter? Thank you

What you're going to need is part # 118158.

To convert from combined wiring on your tow vehicle to seperate wiring on your trailer you will install the # 118158 on your trailer's wiring between the trailer connector and the lights. Connect the wires as such:

From trailer connector to Input side:
Right Turn to green wire
Ground to white wire.
Left Turn to yellow wire

Output side to lights:
Green wire to right turn signals
Red wire to both brake lights
Yellow wire to left turn signals

The running lights circuit coming from the 4-way (generally the brown wire) will bypass the converter and connect directly to the lights.

To make the installation process easier you might like to add a junction box, like part # 38656, to your trailer.
