Electric Lumbar Support Seats, Wiring Harness

[sam.bird3]

I have fitted Electric Lumbar support seats from a 2007 S-Line to my car, The seats removed didn't have electric Lumbar support on them so the wiring wasn't in place. I have found This (http://www.kufatec.co.uk/shop/en/Audi/A4-B6/8E/Seat-Adjustment-Harness-A4-B6/8E) does anyone know if this is the correct harness I need?

Also, if this is the one, then to me it just looks like an Earth and Switched Live feed to power up the seats. Does it not need any Fuses or Relays?

Any help or advice will be much appreciated

My seats have the following plugs...

the red is for the lumbar support but not sure what the black is, the passenger seat only has the red plug whereas the drivers seat has both. Can someone help me ID these plugs??

I'm wondering if the Red Plug is a spur off to the passenger seat and the black one is the power. Any Ideas?

Right,After many hours of searching the Net I think I have an answer.....

It seems that the black plug is a Seat Belt pressure sensor module plug, I'm guessing this is to tell the car if the driver has his seat belt on or not and the reason it's only on the drivers side is the passenger seat doesn't have the sensors fitted.

The red Plug is for the Lumbar support power. This then Leads me to my next question.

Is this loom the correct one from Kufatec??? Kufatec Loom (http://www.kufatec.co.uk/shop/en/Audi/A4-B6/8E/Seat-Adjustment-Harness-A4-B6/8E) and if so, do I need to fuse it or Relay it?

The description says its for seat hight adjustment , are you not fitting lumbar support ?
The plug looks like it will connect thought the pins may be in the wrong location .
If you just need to power the seat why not run your own cables from the fuse box switched via a relay to the seat , it will ony be a live and earth as I assume the control switch is on the seat . I would check the cars fuse chart as it will list the correct fuse rating for lumbar support .
hope this helps
