Remove the Screw there and touch the Purple/Voilet Wire to any of the 2 Terminals to the left (they have + voltage) and you will here your Glow Plug Relay click on.
You will also note the Purple/Violet Wire at the Glow Plug Relay connection.
Also note that this is the same place a Remote Starter Switch can be hooked up to (the yellow arrows).
On other non-turbo Diesel 123 models the Purple/Violet Wire is connected at the Starter Solenoid.

I thought I already explained that my glow plug relay has been modified and I cannot do a proper test and that is why I asked if you can do a test.
Looking at a wiring diagram tells you nothing as to how the glow plug relay operates in regards to the purple wire.
