Hi,
Sorry to resurrect this thread but I’m about to do this upgrade.
I’ve got a 52 plate TD4 auto. I’ve picked up the master switch (actually I have a couple, for the binnacle or the side auxiliary switch panel), the ECU and the steering wheel controls should be here tomorrow.
Where does the ECU live, please? You mentioned under a seat. I’ve just changed my seats from factory fabric to factory black leather with heated front seats (all the wiring for those were present and I just needed to fit the switches near the ashtray).
Anyway, under the drivers seat was a third plug (1 for heated seats, 1 for pretensioner, 1 for.... I don’t know!). Is that what I’m looking for because it only has 2 wires.
I hope I’ve not bought all the bits and dropped a b*****k by not having he wiring loom in place!
Any advice would be great, thanks
