Tekonsha 118461 4-Way Flat OEM Replacement Harness
Tekonsha 118461 4-Way Flat OEM Replacement Harness — Product description
The Tekonsha 118461 is a 4-way flat replacement for your vehicle's OEM tow-package wiring harness. It restores the factory trailer connector that runs your trailer's tail lights, brake lights, and turn signals, so you can plug in and tow again without rewiring from scratch.
The Tekonsha 118461 is a 4-way flat replacement for your vehicle's factory tow-package wiring harness. If the original connector got crushed, corroded, or just plain wore out, this is the part that gets your trailer lights working again without a full rewire.
Here's what it does. It restores the standard 4-way flat trailer connector, the four-pin plug that carries ground, running lights, left turn and brake, and right turn and brake. That's the connector you'll find on most small trailers, utility trailers, and boat trailers. Plug your trailer in and your tail lights, brake lights, and turn signals do what they're supposed to.
This is an OEM-style replacement, so it's built to match the harness that came off your vehicle. Tekonsha lists it covering model years 1998 through 2008. Before you order, take a look at the connector on the harness you're pulling out and match it up. Fitment on tow-package harnesses is specific, and the factory plug is the surest way to confirm you've got the right one.
One thing worth being clear about. A 4-way flat carries lights only. There's no circuit here for electric trailer brakes and no dedicated 12-volt charge line. If you're towing something heavy enough to need brakes, you'll want a brake controller and a heavier connector, not this harness. For lights-only trailers, though, the 4-way flat is exactly right, and it's the most common setup out there.
Who's this for? Anybody who tows a lights-only trailer behind a vehicle that left the factory with a tow package. Landscapers running a utility trailer, weekend anglers hauling a small boat to the ramp, folks with a cargo trailer that needs its lights sorted out. If your factory 4-way plug is the problem, this is the fix. And because it's a direct replacement, you're not guessing at wire colors or chasing a ground fault through the frame.
Tekonsha has been building towing electronics for a long time, and they know this corner of the market cold. The 118461 is a straightforward, no-drama replacement part. Get the fitment right, plug it in, and you're back on the road.
