How do I wire a '71-73 911 turn signal switch into '71 914 harness Options

[morehills]

Now that the structural changes are done on my GT interior, I'm moving on to wire in the turn signal, ignition and wiper switches. It makes my brain ache to study the wiring diagrams from my '71 914 (early 12 pin harness), and the 1971 911 and 914-6 diagrams. Differences between them all and I'm a less than proficient electrician.

Here's a chart I made for the turn signal and ignition connections (thanks to Jeff Bowlsby, Clay Perrine and Tom Butler for groundwork posts and advice):

My biggest remaining questions go to a couple wires from the 911 turn signal harness that run outside the 914 12 pin connector.

I've labeled them in the chart above as position 15 and 16 (on the right). 15 is a red/white wire which runs from the switch bundled with the parking light wires, and from the 911 diagram it appears to be always on power connecting to the light switch. And 16 is a black wire coming back from the 6 prong plug. Can anyone confirm how they are used?

I'd be very appreciative of anyone who has put a 911 column in an early car helping me out. Am I on the right track or just smoking it?

Thank you,

John
