It is important to match the electrics to how you will be using your tow bar. For instance if you are towing a caravan the electrics would need to be different to those for a cycle carrier for instance.

We at TrailerTREK can give you advice but for your information here is what you need to consider.

STEP 3 - Choose which tow bar wiring option you want from universal wiring or dedicated wiring

For any tow bar there are 2 ways the wiring can be fitted.

On older vehicles you have the option to fit universal aftermarket wiring as well as dedicated specific wiring but with some newer vehicles only dedicated specific wiring can be fitted. Universal wiring can often be cheaper but cheaper is not always best. For example universal wiring may not activate inbuilt safety features. On going all new cars will require dedicated specific wiring.
