80 Series Landcruiser Plug-and-Play Trailer Wiring / Rear Bar Lights Wiring Harness

If you're looking to add trailer wiring and/or rear bar light wiring to your 80 Series Landcruiser, or simply want to clean up a bad install, then look no further than the Trail Teq Plug-and-Play Trailer / Rear Bar Lights Wiring Harness.

This harness is designed to plug directly into the OEM underbody loom located at the rear crossmember. See the compatibility tab to confirm fitment. 

Featuring waterproof Deutsch connectors, and thick double insulated fire retardant and chemical/mechanical resistant sheathing with marine grade dual wall heatshrink, our trailer harness and rear bar harness is overengineered to last in the harshest conditions. 

This harness is compatible with 80 Series Landcruisers that came with the Dual 2 Pin and Single 3 Pin breakout plugs on the rear crossmember harness. 

Please check your rear crossmember harness prior to purchase and send us an email if you are unsure of where to look.

Some European 80 Series Landcruisers come with a 2 Pin + 6 pin breakout plug. We are working on releasing a version to suit those vehicles as well. 

This harness is not compatible with models that came with the Dual 2 Pin and Single 6 Pin breakout plug setup.

The main harness has 7 wire provisions:

1. Park Light (Tail Light / Number Plate)
2. Stop Light
3. Reverse Light
4. RH Turn Signal

Both rear combination lights include provisions for Park Light, Stop Light, Reverse Light, Turn Signal and Ground. Pigtails are supplied for you to hookup to your existing lights. 

All of our harnesses come standard with a waterproof Deutsch connection at the plug end for ease of service, installation and removal. There are several options available depending on your location and needs:

• Standard + Add on a Prewired 4 Pin Flat American Spec Plug (with Converter Box)

There is also the option to add a Rear Bar combination taillight T-harness onto the standard main trailer harness. This can be used by itself if you only have rear bar lights to wire up, or can be used in combination with a trailer plug as well. 

The rear bar harness will allow you to hook up a pair of combination taillights (tail, stop, indicator, reverse) as well as a number plate light, in addition to having a functioning trailer plug. Everything is included and is plug-and-play, you will just need to connect your lights to the harness pigtails. 

The rear bar harness features waterproof deutsch connection pigtails with 1 meter of wiring for each tail light side, and 1 meter of wiring for the number plate light. 

If you require a different plug, or another type of custom harness option, then send us an email and we can more than likely help you out.

Comprehensive instruction manual with wiring diagrams provided. 

Each wiring circuit on this harness is rated at the standard 10amps, allowing safe hookup of both traditional Halogen or modern LED globes. 

If you install LED tail/stop/turn signals onto your trailer or rear bar, you may also need to add your own load resistors otherwise the turn signals will blink too fast. This depends on the specific tail lights you use, so make sure to consult their own specific data. 

These harnesses are made to order. Please allow 5 days manufacturing time prior to shipment.
