coil wires

Finished rebuilding the left engine bay wire harness.  Looks like I didnt make enough notes and need to know what wires go to the coil in my 6.9.

I have a few wires from the diag port as well as some from the connector from bottom of the ignition module.

Looking at the wire diagram just confuses me...

Can someone please draw out these wires?

I'm assuming you have a breakerless ignition system.  If so, then this diagram might help.  I'm not sure if this is the one you were looking at or not.  Though, it seems pretty straight forward.  If not, maybe someone else can hand draw it for you before I can.  Or, if there is something in particular you don't understand maybe ask?  Always happy to help.

Robert, I assume that your rebuild followed the original color code?  Sorry for even asking....  ::)  Anyway, I went through the same thing a while back and have many pix of the whole area in question.  Far too many to post.  If you can list the color of the dangling wires and where the other end goes then maybe I can trace them in the pix.  My car is in storage so I can't just go look.  Glad to see the continuing progress.....  Cheers,

Actually the colors are in the shematic , but realised they are in german so maybe you didn't notice them , the letters on the traces are always the wire colors :
sw = black
rt = red
ge = yellow
gn = green
br = brown
vi = purple
so for example sw/rt just means the cable is black and red.

Finally got the wires arranged properly with the help of grandaughters colored pencils.  :D
