My question is will there be an additional plug tucked away under the headlining or do I need to splice one in and if so what connector/plug do I need?
Done this myself and I did happen to find a plug hanging out on the column, so you can always check first
would like to get me 2 of those, 1 for each side.
mine is a 2000 L-series I've been slowly upgrading with later ones commodities,Doesn't your passenger side already have one?
If it doesn't you'll have to order one from a UK vendor and one from Europe
