1994 850 heated seat switch wanted

[rowleray]

Hi
Has anyone got a heated seat switch for my year, 1994, 850 please? (Estate T5 = not significant I assume)
It needs to have only 4 electrical blade connectors on the back, the newer switches seem to have 5
I assume years up to 94 only?
I think the part number will be
3545790 - right side, ideally what I want
3545789 - left side, will do
Rear seat switches, I think will be the same?
Left / right 3523717 / 8

Hope someone can help

Ps the codes that start 914——- are from later models, 5 blades, I’m told won’t work for me?
