The best route for having brake lights, turn signals, and running lights on your trailer with an Australian 7-way is to use the Vehicle to Vehicle Tail Light Converter # 118158. With this system, this will split up the wiring signals for your brake lights and turn signals on the left and right side. For installation, you will have to splice into your current wiring setup. I went ahead and attached a photo that shows the a 4-way wiring setup to give you a good idea of the process.

Thanks so much for the photo. Now that your setup is clarified, we unfortunately do not have an adapter that does not require hardwiring into your setup. With that being said, you need to use the 7-Way Molded Trailer Wire Connector, 4' Long # H20043. The plug end will go with your U.S. 7-way and you will use the wired ends to hardwire it to the adapter # 118158. Once that is complete, you will have to remove the European plug (from your picture) and use the wiring on the adapter to hard wire onto your trailer wiring.

To add a third brake light to a trailer is pretty simple, but does require an adapter to convert the signal. Because trailer tail light systems combine the stop lamp and turn signals for each side onto a single circuit, you will need to use a…

Answer 7

To make an adapter like you are looking for would require the part #H20043 which is a 7-way with 4 feet of wires that you could then wire to a 7-way male like part #A7WCB. I attached a chart that shows the wiring colors for the #H20043 plus a diagram…

Answer 8

You are on the right track. You will need to convert the 4-way to a 7-way so that you can tap into the 12 volt accessory circuit of the connector to power the utility light. For a 7-way with a 4 foot long section of wire you would want the part…
