This diagnostic tool plugs directly between your vehicle and caravan to show you exactly which wire is holding back. You will instantly see whether the fault lives in the car harness or the trailer wiring itself.\u003c\/p\u003e\n\u003cp\u003eThe compact black ABS body grips each terminal securely inside. Carefully machined copper needles pair with your system’s female pins to maintain steady contact. Simply slide the unit into place and press the yellow trigger button. Standard 12V power flows through each pin automatically. Watch the built‑in LEDs map out every signal from left and right turn indicators to running lights, brake circuits, and reverse lamps. A glowing LED means clean power delivery. An LED stays dark to flag a loose connector or cut channel.\u003c\/p\u003e\n\u003ch2\u003eBenefits \u0026amp; Quick Tips\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003ePre‑trip safety check:\u003c\/b\u003e Run through every lamp before hitting long hauls to avoid sudden signal failures.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eGlovebox ready:\u003c\/b\u003e Pack the compact unit alongside documents for instant roadside diagnosis.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eProtect the contacts:\u003c\/b\u003e Store the device in a dry drawer when not towing to keep the copper tips clear.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eCompatibility:\u003c\/b\u003e European 7‑pin N‑type trailer sockets\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eOuter Shell:\u003c\/b\u003e Durable ABS plastic with a frosted black finish\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eContact Points:\u003c\/b\u003e Cross‑slotted copper needles for firm terminal grip\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eOperating Voltage:\u003c\/b\u003e Standard 12V automotive supply\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eDimensions:\u003c\/b\u003e 20 cm × 6 cm × 5 cm\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eNet Weight:\u003c\/b\u003e 0.18 kg\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePackage includes:\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e1 × 7‑Pin Trailer Socket Tester\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eImportant Reminders\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eCut power first:\u003c\/b\u003e Switch off your vehicle before attaching or removing the unit to prevent electrical shorts.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eDry hands only:\u003c\/b\u003e Avoid touching exposed metal pins while testing live circuits to maintain safety.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eSystem limits:\u003c\/b\u003e Designed strictly for standard 7‑pin trailer setups, not commercial eight‑wire configurations.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cb\u003eLanguage Support:\u003c\/b\u003e English interface and functional labeling provided.\u003c\/p\u003e\n\u003cp\u003eAll electronic and mechanical equipment, devices and machines sold by InterCyprus to EU countries are CE certified and carry a two year warranty.
