Help with some wiring for 1968 Dodge Dart

Hi, Im currently working on my cars wiring, preparing to drop the engine in with new alternator, distributor, electric SPAL fan etc, and also checking through what works in the car.
So far I have bought a relay that seem to fit for the headlights (probably got installed by dealer when imported to Sweden, long dark winter nights here), but the relay was missing when I got the car so I´m a little lost as to which connection go where.

Now, this is the relay:



Update: I got the wrong relay, its supposed to be 30 -> 87a (low beams), when triggered 30 -> 87 (high beams), se pic.
Now I just need to find where to triggered it so its permanent triggered (stick button is spring loaded and will release)



There were 4 cables in the same sleeve and then another that lay close to them, the first 4 are connected as follows:
30: Power
87/87: To high/low beams
86: Dont know where this one goes, probably light selector switch?

And then there is the fifth cable, connected to 85, that seems to go to the turn signal stick button, picture:


Is that cable supposed to be connected to the relay? If not, what is it for?
I guess it´s supposed to be spring loaded, but the spring was broken, so I need to get a new one.
I guess the button is not for the high beams since it wont stay pressed in, so where do I turn on the high beams?
The light selector switch has three positions, off, parking lights and low beams, but I cant find any button for high beams.

Update: I found the button for the washer motor, its the knob to the right of the light switch, so In the wrong position but at least I found it
Also, I cant find any buttons for the windshield washer motor. I have a windshield wiper knob with three settings (off, slow, fast) which works, and I can push it in (springloaded), but when I push it in I dont get any voltage to the motor (washer motor works and I´ve checked with a voltmeter). But the pump motor wont start no matter where I push.
Any idea where that could be?
