Quick notes and tips
Always check the socket wiring matches your vehicle before installation. The unit is waterproof, but keep the contacts free from heavy corrosion for best results — a quick clean now and then saves hassle later. It’s compact and lightweight, so mounting is usually simple; a small bracket or the existing towbar plate will usually do the trick. If you’re facing a completely dead circuit or vehicles with complex electronics, have a word with an auto‑electrician — it’s often worth the peace of mind.
