SWB Ignition Switch Wiring

Hopefully someone can help me. 68 911 that I'm trying to reinstall the ignition switch. It looks like this:



The terminals are labeled 30 (double), 50, 54(15/60), P, and R.

Here's the wiring diagram:



You can see the numbers in the wiring diagram don't match up the the labeling on my ignition switch.

30 seems to be straight-fwd. It get's the 2 small red wires...one from the steering column and one from the light switch.

50 is easy...yellow goes there.

I assumed the large red wire goes to the 54(15/60) because there was "15" there.

I've got a wire to the radio. I assume it was "R". Lastly, I connected the gray wire from the steering column to "P".

However, when I turn the ignition switch to the radio on position, the radio doesn't come on. When I turn to the "on" position, the coil starts going and radio comes on then. (The engine is not in the car so I can't test the starter.)

I just have a feeling that it's wired incorrectly. Anyone with this ignition switch have the correct wiring?

I solved it. The wiring I show above is correct:

30 - 2 small red wires from light switch & steering column
50 - yellow
54 - large red
P - gray (turn signal)
R - red/wh (radio)

Key positions:
K @ 12 o'clock - OFF. P gets 12+
Turn 1/8 - Radio on. R gets 12+
Turn 1/4 - all off. You can even take the key out.
Turn 3/8 - all on
Turn 1/2 - starter engaged

My issue was the red wires going back to the fuse. The large red wire should go to Fuse 1. The small red to fuse 2. I had them reversed.
