thank you John F
thank you woody

I realy apreciated your answers.

But I am not clear yet on where the connection is to do.

Here I tried to attach a drawing of what I have discovered till now.

the green spots are the holes in the connector (after the battery)
and the red texts are those I found on the back of my relay.

Now the question is : between wich letters is the bridge to do ?

regards,
