3.45V alt on v7?

[Headly]

Are there any other alternates for the power wire on a version 7 motherboard for a messiah install. I know of the main one and the alt that are stated in the install diagram. I also know that I could use the 3.45V for the color fix, but I would like to leave this open for the fix. I am trying to change my magic chip to a messiah and the first two power spots just aren't working. I had gotten them to stick just a little but the wire pulled off. Tried soldering again and the connection gets worse and worse. Please help, thank you.
