Ultimate Overview of the Standard Trailer Light Kit with 25' Wire Harness Video

I believe you already have seen the attached diagrams that are on this page, but I think your best option will be to watch the install video I attached for the trailer taillight kit part #TL29BK which will walk you through the whole process.

Four flat trailer wiring, also called 4-pole wiring, uses four wires and pins configured as shown in the linked photo of a trailer side 4-pole connector. The one pin that is different from the other three (on both trailer and vehicle side connectors)…

Typically 4-way wiring consists of 18 and 16 gauge wires. For a 4-way that has all 16 gauge wire you would want the Wesbar 4-Pole Flat Connector #W787264. The part #HM38138 uses 18 gauge for all wires but the white that uses 16 gauge.

We have the parts you are looking for, but none of our 4-way connector harnesses use 14 gauge wiring as 4-way connectors typically use 16 gauge wire. With that said you can make your own using the Deka Jacketed 4-Wire - 14 Gauge #DW04923-1 which is…

For the 1998 Suzuki Sidekick Sport Model, the Curt Class I, part #C11024 is a confirmed fit. According to Curt, their #11128 Class I hitch is NOT a fit for a Sport model Sidekick. If you'll be using the hitch for light-duty towing, consult the…

Thank you for the photos! It looks like you have the tail lights that come in the LED Combination Tail Light Kit #TLL9RK which means you're needing the Replacement Side Marker Lens #AL9RB.

I would go with the tire size the closest to what you have on the trailer so that you know there wouldn't be any clearance issues at all. Good call in getting rid of the passenger vehicle tires though. That could get dangerous if left on. The…

A light kit like the Optronics Trailer Light Kit, part #TL29BK, for your trailer is a fairly simple installation if you have average mechanical abilities. I am including a link to a video of the light kit being installed on a trailer and another…

Optronics doesn't offer instructions for the #TL29BK trailer taillight kit. However, if you click the link I provided to the the trailer wiring help article, you'll see a wiring diagram showing how the kit would be used to wire a trailer. The…
