I'm guessing it must be 12 & 11 and 15 for GND

Yep, that's right. I'm trying to find my serial to usb connector at the moment, and then I'll check the serial. I've tested the serial, and then I made a bunch of changes for actually using it in the golf cart, and I need to see if I disabled some serial comm from the micro. I was testing each part separately before. Well, the search for my cable now continues. I don't think I have the commands echoing to the screen. Let me see what is going on. I'll be back soon.

aha!!! Yes. It's not getting to the serial communications code, because there is no throttle present, so it's just freezing until a valid throttle is present. You shouldn't need any other inputs connected.

Check!

Connected the throttle wires together.. and now I hear the relays..
And on boot it says:

The Stinky Diaper firmware, ver. 1.0

But it still does not respond to the config command, should it?

I'm checking now. Well, in like 5 minutes, because this laptop doesn't have realterm on it, and I must download it.
