[spinksy]

Now I have soldered 10 wires internally onto the serial port pins (same as in pic)

I have taken the following wire/pin layout drawing from the same website as I got the above picture - a Japanese site.

I just need alittle help with the above drawing - heres how I'm thinking the wires go

serial pin 1 = live - although it dosent need a live does it?
serial pin 2= ??
serial pin 3 = earth
serial pin 4 = to SD pin 7
serial pin 5 = to SD pin 2
serial pin 6 = to SD pin 1 ( and to LED negative?)
serial pin 7 = to SD pin 5
serial pin 8 = (earth)
serial pin 9 = not used
serial pin 10 = live pin of LED? and live pins of 2 capacitors which then go to SD pin 4. (and the negative leg of capacitors go to earth?)

while SD pins 3 & 6 go to earth too.

Is that right? I'm not very good with these types of drawing.

Help is appreciated.

I found this, the replies talk about the serial pins.
