messiah 3.5 volt

[ps2man]

i just got my messiah 2 and am a little confused on the power connection. The messiah 2 site install instructions shows a 3.3 and a 3.5 volt. The picture show the 3.5 is for the NTSC and the written instructions say the NTSC is 3.3 volt. My Question is which voltage is used for the chip and which is used for NTSC? ALso do you need to use a larger wire for the NTSC color fix. Thanks
