THE PORTAL HUB - Pinzgauers, Haflingers, Volvo 303s and more!

Hi guys
I'm new to the forum. My name is Thomas. 30 years old and love tinkering on cars.
I have a project 1972 712m. It needs a heap of work. It came without a starter motor so I bought a new old stock bosch original. Now I can't for love of everything holy figure out the wiring. Because the bosch motor only seems to have 1 connection, the other bolt is painted over.
And since the batterie tray is rusted out it also came without batteries. And puch in all their wisdom use only black wires. I'm quite good at reading diagrams so I pretty much figured out wich wire is plus and which is negative. Eventhough my plus wire says minus on the clamp.
Since I don't want to fry my new starter or other electrics, could someone take some pictures of the starter so I can see where all wires are supposed to go. The diagram shows the 30 and 50 connection, I need a picture which is what.
I have spent hours on the net looking for pictures in several different languages, but no-one ever seems to take pictures of that side of the engine.

I hope you guys can help me. Thanks in advance

let me introduce you to the two versions of starters used in Pinzgauers


the left one is version 1, right one is v2

both have a M8 bolt on the solenoid connected to battery plus 24 volt and negative ground.
the solenoids have one additional connector, where you trigger the starter.

I have tried it, if you misconnect the batteries, the starter still works, you just fry the generator ...

Thanks Guys that's exactly what I needed.
I wonder how I could have missed the little screw to the side.
Now I just have to find the missing black starter button wire.
