puma trailer electrics
puma trailer electrics - i've been quoted 2 hours to fit because the need to do "something" in the dash..

I thought it was simply connecting the lead to the plug behind the plastic panel in the wheel arch ...

any ideas ??

I have no idea, but I would guess that 2 hours to do "something" in the dash will run a pretty franc in the good ol Schweiz...my guess is that they will stick you for over 500 francs by the time they are done. Independent? 2008 Defender 110 60 year Edition (sold unfortunately)

Hi,
You've been ripped off!!!
You can do it yourself in less than 30 minutes. All you need to do is seek out the connector behind the plastic 'shield' on the wheel arch and attach the trailer socket to it - done.
If you are really fussy (and handy with a drill), you may want to mount the trailer socket on to the rear chassis crossmember by drilling 3 small holes by the recess 'square aperture' and attaching the trailer socket with the 3 small screws and nuts - a neat fix!!
Don't let them rip you off.

I think the 'something in the dask' is the the 2nd electrics or fitting a 13 pin plug. There is an ignition feed near the radio so that the trailer does not draw power when the ignition is off.

Standard 12N type 7-pin socket is a very quick job.

12S supplementary socket or a fully wired 13-pin socket probably will take a couple of hours. Both the 12S and the 13-pin sockets include both a permanently live and a switched (ignition on) live which are more complex to install.

If it's for the Euro 13-Pin Towing Connector, then in addition to the 9-way socket under the wheelarch, there's a loom that's run forward to the battery box, with a relay mounted into the battery box and a trigger wire for that relay, taken from a splice into an ignition switched live on the back of the HRW switch.

Should be able to be fitted in less than one hour, especially id it is done at the dealers where they have done them before & can put them on the ramp for easy access. It is so simple you could just buy the parts & fit it yourself. It is worth buying the genuine LR kit as it fits nicely and comes with instructions, all cable ties etc.

Most of the electrics just plug into a connecter under the wheel arch. Another part of the loom has to be run along the chassis into the battery box, where the relay for fridge power it fitted & the constant 12v live for aux power & charging the caravan battery is fitted.(the relay for connecting the caravan battery only when the car is running is now fitted within the caravan)

A single wire is then run up under the dash (instructions tell you to remove the radio for access) and then conected to a switch to the right of the radio, this is for ignition sense. All very easy.

There are two configurations of towing electrics now (apart from either a 13 pin or 12N & 12S) and centres around the caravan battery. In the old days a 'split charge' relay would be fitted which would connect the caravan battery for charging only when the dynamo was running fast enough. With modern alternators this is no longer nessasary. the caravan used to have 3 power feeds, one constant, the other two via two relays. One for fridge and one for caravan battery. Nowdays there is only one relay fitted in the car which feeds the fridge. A second constant 12V connects to the battery for charging but via a relay which is fitted as standard in modern caravans, in turn the relay is operated by the fridge feed which is only on when the car is running.

I know what you are thinking " can I just connect the battery and fridge feed together?" No as the fridge would discharge the battery.

All make sense?

The only problem comes when connecting an older caravan to a car with newer electrics. The simplest way is to mod the caravan electrics to the new standard, the other option is to mod the car. this is what I do, that way I can connect to either system and it will work fine. I is just two wires and another relay, but I wo'nt bore you with the full dtails here.

thanks Niglyn for the comprehensive reply, but I only want trailer electrics, so i think it's only the plug behind/inside the wheel arch.

for trailer electrics only, should take you about 10 minutes. The hardest part is getting at the two screws that secure the plastic liner in the wheela arch. The LR electrics are of the correct length and all pre-terminated both ends so you just plug it in. That is it, job done.
