This Narva Suzi Coil 7 Core 4 mm cable gives you a tidy way to run trailer lights over 4.6 metres without loose wire dragging on the deck. The coiled lead stretches out to around 15 ft when you are hooked up then pulls back in when you unpin the trailer. Seven cores in the harness keep your stop, tail, indicator and auxiliary circuits separate and organised.

The cable runs 6 x 2 mm² conductors plus one heavier 3 mm² earth core to handle return current on Aussie length trailers. Two short tails at about 250 mm each give you room to route into plug mounts or junction points without strain. Metal body plugs matched to Narva part 82161 stand up well to stone hits and general road use. It is solid gear for anyone who wants a neat 7-pin Suzi setup that will keep doing the job.

Q: Is this Suzi coil suitable for a standard 7-pin trailer wiring setup?

Yes, it is built for standard 7-pin trailer circuits. The cable has 7 separate cores so you can run left and right indicators, brakes, tail lights and auxiliary lines. The layout suits the common 7-pin pattern used on many Aussie trailers. Always match the wiring colours and pin functions to your existing plugs when you hook it up.

Q: What is the maximum working length of the Narva Suzi Coil?

The maximum stated extended length is 4.6 metres. That is about 15 ft when the coil is stretched under normal use. This gives enough reach between the tow vehicle socket and the trailer plug on most setups. Avoid overstretching the coil to keep the insulation and conductors in good shape.

Q: Does this lead include both plugs already fitted?

Yes, the standard metal plugs are factory fitted. The coil comes with Narva style metal 7-pin plugs on the short tails. This saves time compared with crimping your own terminals and assembling housings. You still need to check that the pinout matches your vehicle and trailer before road use.

Q: Can the heavier 3 mm² earth core improve circuit reliability?

Yes, the larger earth core helps carry return current. The 3 mm² earth provides lower resistance than the 2 mm² active cores. That can reduce voltage drop on lighting circuits over the 4.6 m run. It also gives a bit more headroom when you add extra loads to the trailer harness later on.
