How to Install a Hitch Pin
Pin through the receiver and shank, then clip fully seated. A missing clip is a classic first-tow miss.

First time hooking up a trailer in Canada? Slow down and treat the first tow day like a systems check, not a race to the highway. This print-friendly walk-around covers lights, chains, the hitch pin, tire-pressure mindset, the first quiet kilometres, and clear reasons to stop. It is shopping-adjacent help from the parts counter — not a substitute for your owner’s manuals or provincial rules.
Built for Canadian first-tow days. Free shipping on CURT towing gear from Lots of Parts when you still need a pin, wiring, or hitch hardware.

All four videos are from the official CURT YouTube channel (@curtmfg). They are primers for the hardware you will touch on tow day — pin, wiring, ball mount, and general technique — not a substitute for walking around your own rig.

Level attitude and the right ball size matter before you load the tongue.

Do this with the truck in park, parking brake set, and someone on the brake pedal when you call for lamps. Take your time. A five-minute walk beats a roadside scramble.
1Coupler and ball
Correct ball size locked on the coupler. Latch fully closed. Safety pin or lock through the coupler latch if your coupler uses one.
2Hitch pin and clip
Pin through receiver and shank. Clip fully through the pin. If you use a lock-style pin, confirm it is engaged — see the pin and chains guide linked below.
3Safety chains
Cross the chains under the tongue so they can cradle it if the coupler pops. Hooks point up. Slack enough to turn, not enough to drag.
4Lights and wiring
Plug seated fully. Check tail, brake, and both turn signals. Clear lenses of snow and mud — common Canadian first-day misses.
Tongue weight and tire-pressure mindset
Tongue weight is the downward force on the hitch. Too light and the trailer can sway. Too heavy and you unload the steer axle. Use the tongue weight explained guide before you guess with a bathroom scale story. On first tow day, aim for a stable, slightly nose-down trailer attitude within the vehicle and hitch ratings — then reassess after you add real cargo.
Tire pressure is a mindset, not a single magic number. Check vehicle and trailer cold pressures against the placards before you leave. Under-inflated trailer tires heat up fast on Canadian highways. Over-inflated tires ride harsh and can reduce contact patch. Recheck after the trailer has been sitting overnight in cold weather — pressure drops with temperature.
Brake controller check (when you have one)
If the trailer has electric brakes, confirm the controller wakes up, the manual override works in a quiet lot, and the gain feels sane before you meet traffic. New to controllers? Read do I need a brake controller. Four-flat wiring alone does not create electric brakes — see the wiring harness guide and four-pin versus seven-pin pages if you are still sorting plugs.
First kilometres — quiet and boring on purpose
Leave the driveway slowly. Feel for sway, listen for scraping chains, and watch mirrors for lamp faults. Stop in a safe lot after a few kilometres and re-check the pin, clip, coupler latch, chains, and connector. Heat cycles and the first bumps settle hardware — a second walk-around is not paranoia.
Keep speeds modest until you trust the attitude and the brakes. Wide turns need more room than you think. Plan fuel and rest stops with trailer length in mind. In winter, give yourself even more following distance and earlier braking — ice does not care that it is your first tow day.
When to stop
Stop
Sway you cannot calm
Ease off throttle. Do not yank the wheel. Find a safe pull-off and reassess tongue weight, tire pressure, and load.
Stop
Lamp or brake faults
Dark brake lamps or a dead turn signal are not “finish the trip” problems. Fix them before traffic densifies.
Stop
Hardware that moved
Missing clip, loose coupler latch, dragging chain, or a connector that walked out — park and correct it.
Stop
Smell, smoke, or heat
Hot brakes, burning rubber, or a tire going soft means you are done towing until it is diagnosed.
Print-friendly checklist
- Owner’s manuals for vehicle and trailer reviewed for ratings
- Ball size matches coupler; latch closed and secured
- Hitch pin through shank; clip (or lock) fully seated
- Safety chains crossed under the tongue; hooks oriented up
- Wiring plug locked in; tail, brake, and both turns verified
- Tongue weight and load within ratings; attitude looks stable
- Cold tire pressures set on vehicle and trailer
- Brake controller checked if the trailer has electric brakes
- Mirrors adjusted for trailer width
- First quiet kilometres planned; second walk-around after a short stop
- Clear personal rule for when you will stop and reassess
