Help with some wiring for 1968 Dodge Dart

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?
but I cant find any button for high beams.

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),

If there is a switch on the signal lever it is not factory in the U.S. so no idea what it might be. Does your country require a high beam "flash" function? The original dimmer switch is/ was a large metal button mounted on the left side of the drivers floor

Something like this



Your washer switch IS the wiper button which you push in. If you are not getting power there, it's right there in the switch, or the wire continuity out through the bulkhead to the washer unit. You must have the key in run or accessory
