-In this diagram (and, it should be noted, the official Nintendo RGB lead), SCART pin 8 (aspect ratio switching) is permanently connected to 12V. This will tell TVs that listen to this signal that the aspect ratio of the picture is 4:3 (as any signal between 9.5V and 12V will). If you have a suitable TV and want it to work at 16:9 by default, this pin needs to be brought down to between 4.5V and 7V (6V nominal). A voltage divider should probably be used for this purpose, but a single resistor will also probably work with a bit of information about the probable internal resistance to gnd of SCART pin 8. I have seen this listed as >​10Kohms,​ but how stable the actual value might be between different TVs is very difficult to say. Alternatively,​ of course, you could just use the 5v signal from pin 4 of the Wii connector.+In this diagram (and, it should be noted, the official Nintendo RGB lead), SCART pin 8 (aspect ratio switching) is permanently connected to 12V.

-Information suggests (see section above) that Wii pin 16 actually contains information about the aspect ratio currently being provided, but the voltages present are not compatible (in magnitude or orientation) with those required for SCART switching to operate. NB: Since I wrote this, I have discovered that other experimenters are reporting that this pin does NOT alter it'​s ​voltage in units of several regions - the conjecture is that it will ONLY operate as expected in Japanese units where the D-terminal cable is used.+Information suggests (see section above) that Wii pin 16 actually contains information about the aspect ratio currently being provided, but the voltages present are not compatible (in magnitude or orientation) with those required for SCART switching to operate.
