Please could someone advise whether its feasible to add rear electric windows to a Peugeot 406 Diesel LX. Has anybody tried it and does it already have the wiring for it? I’ve heard that the lower spec models have all the wirring but not the features.It has central locking so I assume it’ll have the extra wires with that. Can I also add the lcd display for temperature and other features to the dashboard. Thanks Saj
