Review of Optronics Wiring A40W5B


Today, we're going to review part number A40W5B. This is the Optronics 40-foot wishbone 5-way trailer wiring harness. This, you can see, has a 5-way flat trailer end connector here already built in, uses the size 20 gauge wires in this. It is a 40-foot long harness, has this additional 30-inch long ground white wire with the eyelet on it to get a good, clean ground, and it also contains this 5-foot long reverse light blue wire, which is usually used to disengage a surge break coupler. Typically what happens on a 5-way flat connection, it's normally used on trailers with surge breaker hydrolic brakes and basically, this additional blue wire would be tapped into your reverse light circuit to disengage that couple or actuator when the vehicle is in reverse, thus turning off your trailer brakes so they don't get activated. This is a wishbone wiring harness and basically, what that means is they have a taillight wire running down both sides of the trailer. The taillight wire goes along with the yellow turn and brake signal wire and the green turning brake signal wire. It makes it more efficient way to wire your trailer. That should do it for the review on part number A40W5B, the Optronics 40-foot wishbone 5-way trailer wiring harness.
