Seven Pin Trailer Socket and Power

Generall when the seven pin plugs are wired for power they use the reverse light wire or the service brake wire. Probably the reverse light wire as many caravans have electric brakes these days and I see from the Pioneer website that electric brakes can be fitted to their trailers.

Look up www.hella.com.au They have wiring diagrams for all type of plugs for towing. Usually they use pin 2 as power, but it most likely not the most efficient way to charge the trailer battery. It should be wired independantly with heavy wire and an anderson plug. You will not have any problems if it is wired this way.
The trailer plug will work...but it could be better!!

Agreed. Using the 7 pin to run a fridge or lights is no worries, but you may be wasting your time trying to re-charge a battery through it.

Every trailer or caravan we've ever towed has the reverse line rigged to 12v. This has only ever been used for low-current devices such as internal 12v lighting .....and sometimes the fridge. If a battery system is installed in the camper, then an Anderson socket has been wired in with solid (at least 6mm) wiring on a separate route straight from an isolator in the vehicle.

Hi,

If you can give me your email address, I will send you some GIF images of 7 pin wiring diagrams.

Cheers

I have a pioneer.
The power is on pin 2 - reverse pin.

The power is supplied to a small Arrid 12v-12v charger.

It is designed to boost voltage from cable losses.

Only used to charge a small SLA battery. Originals are 7A/H - I fiited an 18 A/H.

Hope this helps.
