  • Where Does Sliding Lock of 2019 Triton EZ Loader Trailer Mount on the Tongue?
    The Optronics 7-Pole Blade to 5-Pole Flat Connector Wired Trailer Adapter - Coiled Cable - 94-1/2" Long # A57CCB will work with your trailer wiring. The 5-way on your trailer will have the reverse light power that will on the trailer connection end connect to the reverse lockout solenoid of your coupler. I've attached a photo of the underside of the coupler that has that reverse lockout wire coiled up underneath. This will electrically stop the fluid flow to allow you to back up your...

  • What 7-Way to 5-Way Adapter do I Need to Tow a Boat Trailer on My 2021 Audi Q5?
    The adapter you need to adapt a 5-way boat trailer to your 7-way on your 2021 Audi Q5 is the 7-Pole Blade to 5-Pole Flat Connector Wired Trailer Adapter - Coiled Cable # A57CCB. If you do not need the cable, you can get the cable-less adapter as well. That is the Adapter 7 Pole to 5 Pole Flat - Molded # A75TB.

    Yes, there is an adapter to plug your 5-flat boat trailer connector into your 2016 Ram 2500's 7-Way. It is the Mighty Cord 7-Way RV Style to 5-Way Flat Trailer Connector Adapter item # A10-7275VP.

  • Available 7-Way to 4-Pole and 5-Pole Wiring Adapters
    Yes, a 4-pole flat type trailer connector can mate with a 5-pole flat. The additional circuit on the 5-pole side would obviously not be connected. But we do have 7-way to 4-pole cord-type wiring adapters too, similar to 7-to-5 adapter # A57CCB, such as # HM47065, and # C57271. We also have plug-style adapters such as # HM47570 that convert a 7-way to 4-, 5- and 6-pole, all in one product. All wiring adapters are shown on the linked page.

  • Parts Needed to Make Custom 7-way to 5-Pole Wiring Harness for Light on Bike Rack
    To complete your wiring with a 7-way cord, taillight converter and 5-pole connector I recommend using a few other similar items to give you a cleaner and potentially more reliable setup. Instead of cutting part # A57CCB you could use coiled 7-way plug/cord # WG54006-043, converter # 118158 and 5-pole vehicle-side connector # HM47900. To make the wire connections you can use butt connectors # DW05744-10.
