7-Way Trailer Connector Installation on 2014 Toyota Land Cruiser 76 Series
Question:
Hi There - I have a 2014 Toyota Land Cruiser 76 series overseas not sold in North America and I need to install a 7 wire socket for trailering. I dont think the vehicle has a towing package, so I wanted to install relays as well to avoid burning up the circuits. Is this something you offer, a 7 wire socket with a relay kit for the lights and signals?

We don't offer a relay kit that would work for your Land Cruiser, but I can explain how to wire it so that plenty of circuit protection would be provided to protect your vehicle from any wiring faults that might occur on the trailer.
Keep in mind that my response assumes that the trailer you'll be towing uses a 7-way blade-style trailer connector typical of the US market, like part # A7WCB.
The first step would be to determine if your Land Cruiser has a Separate or a Combined taillight system. A combined system uses the same taillight bulb for the turn signals and the brake lamp, while a separate system uses a separate bulb, usually amber in color or with an amber lens for the turn signal.
In either instance, you'd use the same wiring harness. I'd recommend the # C59236, which will hardwire directly into your taillight circuits. If your vehicle has a separate lighting system, you'd wire harness as follows:
Yellow wire to left turn circuit
Green wire to right turn circuit
Brown wire to running light circuit
Red wire to brake light circuit
White wire grounded to vehicle frame
The Black wire would be ran to the positive battery terminal.
If your Land Cruiser has a Combined lighting system, you'd wire exactly as shown above, with the exception of the Red wire, which would also be grounded to the frame like the white wire.
The # 119147KIT helps isolate the trailer wiring from the vehicle wiring, thus providing protection. The harness draws the power needed to power the trailer lights directly from the vehicle battery, rather than through the taillight circuits, which offers another layer of protection.
The # 119147KIT would provide a 4-pole trailer wiring harness, and you'd use a # 37185 adapter to convert it to a 7-way blade-style trailer connector. How you proceed at this point will depend on whether your trailer has electric brakes or not. If your trailer doesn't have brakes, you'd plug the adapter into the 4-pole, and ground the loose white wire. If your trailer has reverse lamps, the purple wire would tap into the reverse lamp circuit on the vehicle. If the trailer needs 12-volt power from the tow vehicle for accessories like interior lighting, the black wire can be ran to the positive battery terminal via a 40 amp circuit breaker like part # 9510. The blue wire would just be bundled up out of the way, as would be the black and purple wire IF they're not needed.
If your trailer has brakes, and you want them to actuate, you'd need to install a brake controller. More often than not, I recommend the Tekonsha Prodigy P2, part # 90885. The controller strikes a good balance of price versus performance, and it's very easy to use. You'd install the controller using our Brake Controller Installation Kit, part # ETBC7. The kit contains everything needed to install you controller, including the # 37185 adapter mentioned above. Also included are all the wire, hardware and circuit breakers that are needed. The # 37185 would install as mentioned above, with the blue wire carrying the output voltage from the brake controller.
I'll link you to some install details, help articles and install videos that will help you through the install process. The videos show an install on a different vehicle, but the process would be very similar.
