Video Transcript for Optronics Wiring - Wiring Adapters - A57CCB Review

Today we're going to take a look at the Optronics Seven-Round to Five-Flat Coiled Cable Adapter. Now, this will convert your tow vehicle's seven-way blade connector into this five-way flat pin connector. It is a coiled cable design. If you notice on the seven-way, it has a nice finger pull design for easy plug-in and easy removal. On the five-way flat end, it includes this threaded mounting bracket right here, that you can pull as much cable out as you need. Once you get it, you can see it just comes apart when you mount that.

Once you get it to how far you want it out, if you tighten that down, it will keep it at that distance. You can just put it wherever you, once you mount it, adjust it to wherever you need it. That should do it for the review on the Optronics Seven-Round to Five-Flat Coiled Cable Adapter.

Super product from a super online store! I have bought two of these now and will probably buy more as I switch over all of our trailers. You can even remove the five flat end to hard wire it in to the trailer wiring. 734157

This looked to be a direct replacement for an aging wire harness on a Boatmate trailer. Received it today and tested it out. The harness physically and functionally is a match, worked like a champ (Running, brake, RT,LT, Reverse). 482193

Ask the Experts about this Optronics Wiring

  • 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.

  • 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...

  • 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, # C57271 and # MT70086. 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.
