You can fit a tow bar yourself with the right tools, without needing an RDW inspection. You’ll need a suitable tow bar, a wiring kit and a free afternoon. The most important thing is to check in advance which type of tow bar fits your car and to ensure you comply with the legal requirements regarding number plate coverage and maximum ball load. Below, you can read about the different types of tow bars available, the step-by-step installation process, how to connect the wiring kit and the laws and regulations you must comply with.
What types of tow bars are there?
There are three types of tow bars: fixed, detachable and retractable. A fixed tow bar is the most economical option, but may partially cover the number plate. A detachable tow bar can be easily removed when not in use, ensuring the number plate remains visible at all times. A retractable tow bar swivels away behind the bumper, so it’s always to hand without being in the way. Not every type fits every make and model, so check compatibility beforehand.
What tools do you need?
To fit a tow bar, you’ll need a jack stand, a jack or an axle stand to lift the car and create sufficient working space. You’ll also need open-ended spanners and a ratchet to remove the rear bumper. Apply WD-40 or another water-repellent spray to the mounting points to make removal easier. Most cars have pre-fitted mounting points for a tow bar; if this isn’t the case, you’ll need to drill them yourself using a drill. Also keep a torque wrench to hand so you can tighten the bolts to the correct torque afterwards.
Fitting a tow bar: step-by-step guide
When you place your order, you will receive an installation guide, which may vary depending on the make and model. The main steps are:
- Remove the rear bumper. Hold it firmly to prevent damage;
- Remove the rubber caps from the crossbar and clean the mounting points;
- Fit the crossbar to the fixing points and do not tighten the bolts fully until everything is aligned;
- Fit the tow bar sleeve through the side plates of the cross member;
- Fit the plug plate and the tow ball;
- Refit the rear bumper to the car;
- Connect the cable set to establish the electrical connection with the trailer or bike rack.
After installation, check that all bolts are tight and that the electrical connection is working correctly.
Connecting the cable set: 7-pin or 13-pin?
A 7-pin plug is sufficient for a bike rack or small trailer. If you’re towing a larger trailer or caravan, you’ll need a 13-pin plug to ensure a constant power supply. There are universal and brand-specific cable kits: universal kits are cheaper but require more wiring work, whilst brand-specific kits have pre-fitted connectors and work better with the on-board computer and safety systems. Ensure the car is de-energised by disconnecting the battery terminals before you begin, route the cable through the entry point specified in the fitting instructions, and connect the cable set according to the instructions. Activate the cable set using diagnostic equipment. If you do not have this, a garage can do it for you.
Legislation and regulations governing tow bars
You are permitted to fit a tow bar yourself without an RDW inspection, provided you comply with the MOT requirements and the tow bar bears a European type-approval mark. The tow bar must not cover the number plate, not even partially; if this is unavoidable, move the number plate and the number plate light. This is not an issue with a detachable or swivelling tow bar, as you will be using a separate number plate on the trailer or bike rack when in use. Also note the maximum ball load specified by the manufacturer on the type plate and do not exceed it. You can find your car’s maximum towing capacity in the vehicle registration certificate and in the owner’s manual.
