Hello,

I have managed to track down and purchase the elusive R Line leather interior with door cards for my car

This means I will be retrofitting heated seats next week after I pick them up, just in time for winter.

I was looking at the wiring diagram in ciclos post about heated seats but it makes no sense to me. I will be using the Kufatec loom. Which wire goes where

If someone could just draw on the diagram what to plug into where, i will be forever happy.

left: seats
middle: the very small terminal goes to the BCM, the loose wire goes to a blue/grew wire from one of the other buttons next to the hazards, the open loop to the chassis, the big connector to the fuse box
right: two for the heated seats buttons and one big one to the control unit

If you can't find the place where the control unit goes ( from the workshop manual pics ), I can help. It's really not an easy place to reach to, if you want to position it correctly, otherwise, the control unit can be placed wherever.

Also, you don't need that long of a cable ( the loose one, without a terminal , in the middle section ). It's only used for background illumination, so just remove it from the rest of the loom, shorten and keep it next to the switch connectors ( red + orange ), as you'll need to solder it to any other switch wiring aside hazards.

Thanks so much for your reply.

Which pin on the BCM do I need to locate and where is the BCM in a RHD car?
So the loose wire is for the red back lighting?
The ring is for ground?
And which location in the fuse box do I connect the larger pin? Do I need an additional fuse?

The bcm for rhd is located at the driver footwell, right behind the fuse box.

Ok so I now understand one terminal goes to pin 37 on bcm on goes to fuse 36 in fuse box I now wonder where do I get power from? Is that done by daisy chaining the wire for background illumination or do I need to daisy chain of an existing red 12v wire and connect it to fuse slot 36b?
