Heated Seat upgrade
Looking to upgrade to heated seats for winter in my Puma. Is there any factory wiring in the latest models ready to plug straight into or do I have to make up a loom from switch to seat, relay etc etc.

Apologies if this is a boring old question but I did check in search first honest!

The Factory wiring is not that great - the dash switches switch the seat heating elements directly, there are no relays in the circuit Confused

You could make a much better job of it than Land Rover, by using the dash switches to switch relays in the RH underseat fuse box compartment and decent gauge wire to the seats.

If you were using genuine Land Rover seat heaters, a compatible connector for the the vehicle loom side can be bought from a BMW dealer, but it isn't cheap Shocked

A cheaper alternative is to replace the connector on the seat elements with a connector model where both halves are readily available, such as an AMP Econoseal connector, or the larger (2.8mm) 'Superseal' connector.

Try towing a heavy trailer, the seat basses get toastie by themselves, with built in handbrake ankle heater.

Beg to differ about the factory wiring, here are a few facts and figures...

Each seat circuit has a heater element rated at about 14.4 watts at maximum current draw.
Each seat will draw only 10 amps each maximum, being protected by a single 20 amp fuse (fuse 33).
The maximum resistance value of the seat heater element would be 1.2 ohms.
1mm cable in the worse case scenario can carry 11 amps.

My factory wiring for me is ideal and as a sparky I am not about to fit relays as it is functional and fit for purpose! Thumbs Up

If building from scratch relays although 'best practice' are not required in the circuit. If you go through life with your head in the sand....all people will see is an ar5e!!

I'm not disputing that the wiring isn't adequate, it's just a bit too 'minimalist' for my liking.

The wires from the switches to the seat connectors are 0.75mm2 and the terminals in the AMP Sealed MQS connectors are rated to just 7.5 Amps.

Are the heated seats any good or are mine not working? I put my heated seats on to see if they are any good and both the mrs and I could not feel a thing even after 20min. In other cars i've had with heated seats you can feel it almost straight away. 59 reg 90 XS Station Wagon

Takes a few minutes to toast your nads or split kipper but it is noticable. Maybe they're not so noticable in the Summer if the ambient temperature is high? Maybe someone will try theirs and report back.....Or I will next time I drive mine!

Ours heat up fairly quickly. They provide some comfort on a cold morning, just enough to take the edge off the severe cold until the engine warms up enough to provide heat.

Does someone have the part numbers for the heated seat switches themselves AND the connectors that fit them??

For a 09 110

Thanks for any help.

Does this look right?? http://www.rimmerbros.co.uk/Item--i-YUG102430

Does it matter if it is "left" or "right"??

Can't find connector for this???

Missed a good pun there....... Rolling with laughter Rolling with laughter

Well, after nearly needing a change of pants with the pillow talk.... I would only make one mod to my heated seats. That would be to fit a potentiometer so the heat can be adjusted- It takes 5-10 mins to warm up and then another 5-10 mins till it is too hot for my liking.

But then again I am not worried about using them for the next 2 years Very Happy
