Resistor values should be different (but nowadays it is not important so much)
Resistor at Pin 8 SCART can be around 1 - 2k (as this input is rated 10k impedance), Pin16 is rated as 75Ohm thus it can be something around 75 - 100 Ohm
Next info if - level at Pin 8 will be between 5.5 - 7.5V then TV should switch to 16:9 mode. (fastest way to achieve this is Zener diode (6.2 - 6.8V will be perfect).

Oh, please fix Pin16 source - this is TTL level input - anything higher than 5V can damage TV - this is very fast input - reason why it have TTL levels in past it was used as input for something that Amiga output as ZD (Zero Detect) - to switch between two RGB sources - crude genlock (mostly used for external teletext decoders - so called superimpose mode).

Ok with 510Ohm Pin16 should be safe (assuming that this is 75 Ohm input on SCART).
