Tekonsha 118379 4-Way Flat Harness, Toyota Tacoma
Tekonsha 118379 4-Way Flat Harness, Toyota Tacoma — Product description
The Tekonsha 118379 is a 4-way flat replacement wiring harness made for the 1995 to 2001 Toyota Tacoma. It gives you a clean 4-pin flat connector for running your trailer's lights, ground, and turn signals, cut to fit the truck's factory wiring so you skip the guesswork and generic splicing.
The Tekonsha 118379 is a 4-way flat replacement wiring harness built for the 1995 to 2001 Toyota Tacoma. If your truck's factory tow wiring has gone bad, or you just need a clean 4-pin flat connector to run a trailer's lights, this is the part that gets you sorted without a bunch of guesswork.
A 4-way flat is the workhorse connector for small trailers. Four pins, four jobs: a ground, running and tail lights, left turn and brake, and right turn and brake. That covers most utility trailers, small boat trailers, and light-duty haulers that don't run electric brakes. If you're towing something modest behind an older Tacoma, this is almost always the connector you're looking for.
Because it's designed as a replacement for the OEM harness, the 118379 is model-specific. It's cut for the Tacoma's wiring layout from that era, so the connector and lead lengths match what the truck expects. That means less improvising at the bumper and a cleaner result than a generic universal kit spliced into your taillight wiring.
Who's this for? Anyone with a first-gen Tacoma who tows a small trailer and wants dependable lighting. Maybe the old harness corroded out after years of road salt. Maybe a previous owner butchered the wiring and you want to start fresh. Either way, matching the harness to the truck takes the headache out of the job.
A couple of honest notes. This is a lighting harness, not a brake-control setup. A 4-way flat doesn't carry a circuit for electric trailer brakes or a reverse light, so if your trailer needs those you'll want a 7-way setup and a brake controller instead. And double-check your model year. This one's built for the 1995 to 2001 Tacoma, so confirm your truck falls in that range before you order.
It's a Tekonsha part, and Tekonsha has been doing towing electrical for a long time. You get the right fit, the right function, and the backing of a name that trailer folks trust.
