Complete Breakdown of the 20 Ft 4-Way Trailer Wiring Harness Video

The 5.30-12 tires, being wider, are going to make more contact with the road. This means that the noise, and heat build up will be higher than a 4.80-12 tire but the rolling resistance will actually be less because the tire is larger diameter. The…

We do offer a wide variety of replacement lights for trailer but since trailer manufacturers don't keep a record of what they use on trailers I would need some pictures of the lights you are wanting to replace along with some measurements so I…

Your 4-pin/5-wire wiring harness is what is called a "wishbone" type which simply means that there are two separate running light wires, one brown and one pink. This allows a separate running light wire for each side of the trailer which…

It looks like your trailer is wired with a wishbone style harness like the #A20WB. This harness uses two brown running light wires to allow you to wire the trailer running lights without running a jumper wire from one side of the trailer to the…

Going by the colors that you mentioned, it sounds like you have the typical set-up, green wire for right turn and brake, white wire for ground, yellow wire for left turn and brake, brown with green wire for right side running lights, and brown with…

With two brown wires in your photo it indicates a wishbone harness basically allowing running lights to be sent to each side from the coupler location instead of using a jump wire from one side to the other. This is very common to use with boat and…

Sounds like you need to redo the wiring of the new 4-way completely. Typically, the green wire runs to the right turn/stop circuit, the yellow runs to the left turn/stop circuit, the brown wire runs to the taillights and the white is the ground that…

Since LED lights do not require a lot of amperage you can go with relatively small wire. Using 16 or 18 gauge wire will be fine. Harness #A20WB uses 20 gauge wire which is on the small side but certainly not a problem at all for LED lights even…

There are two different types of trailer hubs that will determine if the pilot hole on a wheel matters or not. First there are hubs that use wheel bolts to secure the wheel to the hub. These are called hub-centric. For this type, the pilot hole has…

To measure the width of a trailer wheel you will measure from where the tire beads will seat on the wheel. That will be from the inside of the inner wheel flange to the inside of the outer wheel flange, not from edge to edge of the wheel. To measure…

The length of wire desired depends on your vehicle connection and your personal preference. You want enough slack for turning, but not so much for dragging as you mentioned. A little extra slack isn't a problem and not enough could lead to stress…
