RGB/SCART Pinout Question

Hi,

I am building a new supergun for myself and I have a query....

On the Jamma connector there is:

N - Video Green
P - Video Sync
12 - Video Red
13 - Video Blue
14 - Video Ground



Now, looking at the scart plug above, I will need to connect:

N -> 11
P -> ???
12 -> 15
13 -> 7
14 -> ???
16 -> +5v with 100 Ohm resistor

Regarding the above:

1. What should P -> ???? be?
2. What should 14 -> ???? be?
3. Is 16 -> +5v with 100 Ohm resistor correct?
4. Am I missing anything?

Thanks!

Assuming mono sound connection, if stereo change accordingly:

10 (speaker+) -> 6 (audio left + mono)
(any Ground) -> 4 (audio ground)
12 (Red) -> 15
N (Green) -> 11
13 (Blue) -> 7
P (Sync) -> 20
14 (Video Ground) -> 17
(any 5V) -> 8

Then bridge scart pins 8 & 16 through a 100 ohm resistor.
