I installed mine a couple of weeks ago. Proper FFRR kit, electrics by (I think) Webasto??

It was dead simple, everything plugs and plays (although I haven't used it in anger yet!) but I did disconnect the battery. No reason not to, it's a 10-sec job, plus (a) you're plugging something electrical in, always best to do that with the power off, and (b) I've changed things on cars before without disconnecting the battery and paid the price!!

I did mine with battery plugged in and had no issues, just no key in the ignition  FFRR MY06 facelift With TDV8 Alloys Zeros/ATR's

Cappo, Westfalia was the company you were thinking of. Webasto do the FBH
