I want to add a lock switch in my E500 and wanted to know if someone has a wiring diagram with some information for the retrofit.

Quick Drawing out of my notes.. Used standart Car "Switch" Relais. Original Switch + Socket and Pins. Relais is mounted next to the pump under the seat.

Works on my EU 1992 500e

The setup shown above will only lock all doors, correct? You cannot use the switch to unlock the doors?

I don’t see why you need two Relais

I tried now this option and checked everything unfortunately it didn’t work. There are 2 blue wires to the pump i guess both have the same option. It there a special relais to be used?

Went into my Barn and Checked everything.. Updatet the Drawing!
It does Lock and Unlook the Doors! but you will have to Push the Switch till it is look/unlooked! not just a short push like today cars.

With a 2nd Relais, you could hook up the LED..

Relais is Standart "Switch/change Relais"

So there is no need to cut the wire just put a wire to 87a
And the red one is what exactly which is going to 30?
