How can I force SCART pin 16 high for RGB?


I just changed my ordinary Sky digibox for a Sky+ model. The SCART pin 16 output of the old digibox was strong enough to switch my Toshiba DR3 into RGB mode but the new box doesn’t seem to switch the Tosh into RGB mode. I’m assuming after searcing the web for a while that the reason for this is that the voltage on pin 16 isn’t high enough to force the composite->RGB switch.

Ther are plenty of sites that tell me that I need to put 1-3V onto pin 16 manually to force RGB mode, but I can’t find any easy to follow instructions on how to achieve this.

Would some kind soul point me in the right direction please?
