Reading Porsche electrical diagrams

[helidoc]

Can someone help me understand this shop diagram for an early 911. I am restoring my wiring harnesses as part of a complete 1968 911L project. Specifically I am trying to understand the small square boxes when wire lines cross. Does this mean they share a connection at that point? In the attached photo which shows the fuse box you can see a white wire with yellow stripes which runs close and left to the box above fuse 12 to fuse 5. There are 3 white boxes along its course intersecting at a white wire going to 12, a black and gray wire at 8 and a red and gray wire at 7. What does this mean in viewing the actual fuse box connections? Thanks.

Sorry tech difficulties posting picture.

You can also find schematic symbols by google images et they are pretty much standard throughout the electrical world

Pic for you. They are not intersections, just wire ends.

Oddity in the pic is the left side of fuse 11 and the two points of of termination, one I understand, second is odd???

Yes, that line coming out is unique. One can choose to terminate at 11 or 12 on the left side as it is a common terminal. (Internally connected as shown by line between fuses)
Junior engineers drew these up.... maybe that was their way of showing the option?

Thanks for the posts. That picture by timmy2 was the exact one I was trying to post as a capture screen picture from a scan I did of the manual. Don't know why it wouldn't work but so glad you posted it and for the explanations. Makes sense that those little white boxes are just wire ends but why not at all the crossings into the fuse box?
