I've got wind up windows in my 6n at the minute and thinking of putting electric ones In I'm just wanting to know how hard it will it be? And also what will I need? I'm thinking the wiring loom, regulators with motors and the switches

Help much appreciated

The regulator mechanisms, door looms and at least the connectors behind the a pillars and switches and connectors behind them.

Although if you could get the whole dash loom it would be plug and play, if not then you would have to make up a loom with the above connectors.
