where can i get the 5V for the dual lm1815 circuit on a 2.2?

The Griffin

On the JP1 connector pin 8.If you are looking at the board so you can read the silk screening (i.e. Db37 connector on the right) JP1 is just on the right side of the main cpu.JP1/8 is the bottom most hole.It's also known as "VCC"(+5V) on the schematics http://www.bgsoflex.com/v22/megasquirt_ShemV2.2.pdf
