Hello,
I recently purchased a set of E90 Sport, power, lumbar, seat heating seats and wanted to install these in my '84 528e. Will I be able to get the seat heating working as my car obviously has no CANBUS or way to generate a PWM signal to the seat heating modules. I have found E90 seat heating switches on Ebay but it looks like the PWM signal is generated in the Juction box? (also do not have.)
Thanks!
(I have gotten all the other power features to work, however!)
