Emax

You don't actually have to wrap the wire. just add a little solder to  
the connection point.
Remove the iron and let it cool for a few seconds.
Reheat and stick  the stripped wire into the molten solder.
Pull the iron away after about 3 seconds and make sure the wire stays  
attached by gently giving a little tug.
if it stays it should be connected fine.
If not, try again. just don't heat any connection for more than a few  
seconds at a time. If not successful, then let things cool down before  
trying again.

Regards,
Ted

Ted,

I received the kit in the mail today. I have removed the PCB from the  
keyboard and is getting ready now to start wiring.

Question: How do I use this wire wrap wire? Do I wrap it on the post  
and then apply a tad bit of solder?
