How to Select a Trailer Hitch
Hitch class still comes first. Converters and harnesses only matter after the receiver and door sticker are honest.
Watch on YouTubeTrailer Light Converter Tips (Canada)
Trailer lights only help if the tow vehicle can drive them the way the trailer expects. Some vehicles get a plug-and-play four-flat harness that taps a module and just works. Others need a taillight converter so combined vehicle stop and turn circuits can feed a trailer that wants separate turn signals. This Canada parts-counter page covers when a converter is the honest answer, LED versus incandescent habits, four-pin versus seven-pin, and how to pretest lights with a tester. We will not invent legal cutoffs.

Trailer Hitch Installation Techniques
Install habits matter for splices and grounds. A converter will not fix a chewed ground or a corroded plug.
Watch on YouTubeHow to Connect a Trailer Wiring Harness
Watch how a harness is meant to connect, then decide whether your vehicle needs a converter instead of a module tap.

Ball-mount height does not fix dark trailer lights. Keep lighting on its own checklist beside the hitch.
Watch on YouTubeConverter versus plug-and-play harness
A vehicle-specific harness is the happy path when CURT publishes a kit that plugs into a tow connector or T-harness points on that year and model. You get a four-flat at the bumper without guessing wire colours. When a dedicated harness is not listed, or when the vehicle uses a combined stop and turn circuit that a standard trailer cannot read, a taillight converter becomes the practical bridge.
In plain counter talk: if the car already speaks trailer language through a module, buy the harness that matches the vehicle card. If the car combines brake and turn into one filament or one LED channel per side, the trailer still wants separate left and right turn wires. That is the job of a three-to-two style converter or a multi-function converter that can also handle pulse-width modulated factory lamps.
LED versus incandescent honesty
LED trailer lamps draw less current than old bulbs. Some older non-powered converters and flasher cans expect enough load to behave. If trailer LEDs hyperflash, stay dark, or confuse a converter, do not keep splicing blindly. Use a converter designed for modern vehicle outputs, confirm grounds, and pretest with a tester before you chase the trailer down the driveway. We will not invent a province-by-province rule about which lamp type you must run.
Factory LED taillights on the tow vehicle can also change which harness or converter is listed. When a product card says it excludes LED tails, believe the card. A powered converter with a clean battery feed is often more stable than hoping a non-powered unit will keep up with low-current or modulated circuits.
Four-pin versus seven-pin
Most light-duty converters on this page end in a four-way flat for tail, ground, left turn, and right turn. That matches a simple utility trailer. A seven-way plug adds reverse, twelve-volt charge, and electric brake circuits. Converting three-wire vehicle lamps to two-wire trailer lamps does not automatically give you trailer brakes. If the trailer needs a brake controller and a seven-way, open the four-pin versus seven-pin guide and the brake controller guide instead of forcing a four-flat to do heavy-duty work.
Pretest habits and wiring tester tips
Before you blame the converter, walk the trailer lights pretrip check. Confirm the vehicle lamps work, the plug is clean, and the trailer ground is solid at the frame. A plug tester or the habits on our wiring tester tips page will tell you whether the tow vehicle is outputting left, right, and tail before the trailer ever rolls. Salt-belt corrosion loves four-flats, so keep a dust cover on the converter output when it sits empty.

Parts-counter notes
| Topic | What we tell shoppers |
|---|---|
| Harness first when listed | If a vehicle-specific kit exists, start on the wiring harness guide before you splice a universal converter. |
| Converter when circuits differ | Combined stop and turn on the car plus separate turns on the trailer is the classic converter job. |
| LED honesty | Low current and PWM factory lamps can expose weak converters. Prefer the multi-function or powered cards when the live notes say so. |
| Four-pin versus seven-pin | Converters here feed light-duty four-way flats. Brakes and charging need the seven-way path: four-pin versus seven-pin. |
| Test before you tow | Use pretrip light checks and tester tips so you know which side failed. |
| No invented laws | We describe hardware behaviour, not province-by-province lighting statutes. |
