If only it was a heated beaded seat cover Rob!

Here's all the WDS diagrams for the E70 heated Seats:

It might not actually be that bad a wiring job. Depending on whether you have a "high" or "low" system to install it's either a case of:

- 2 wires from the JBE module (junction box electronics)
- 1 wire from the JBE & two to the power module.

connected to the seats.

You then have a module under the seat SMFA & these connections go in to it. Then the heated mats connect in to that SMFA module.

Thanks Mark, that's a great help.

I do have one query, do you know the difference between a "high" and "low" system?

I was planning to fit the e90 seat pads so I wonder would they determine if it is a "high" or "low" system or is it something else?

Thanks
John

This article describes two types of e70 heated seat options. http://www.bmwmotorsports.org/pdf/e70/05a7_E70%20Seats.pdf

The basic one (as fitted to sport seats) has 2 circuits and the more complex one (as fitted to the multifunction seats ) has 4 circuits. I presume this is the difference between the "high" and "low" systems.
