So I finally got my FTDI breakout board I ordered from Sparkfun. So I hooked it up right away and it works again, finally.
Here is a pic of it
I hooked the Gnd, TX, RX, and DTR pins up. I didn't hook up VCC, because I only need the FTDI board powered when I want to upload, plus then I can use the USB power to disconnect anything else that is on the same serial port automatically.
So pinout is like this:
FTDI - Arduino
Gnd - Gnd
TX - RX
RX - TX
DTR - DTR
I also had to remove the solder joint beside the FTDI chip to disable the 3.3 volt, and then I soldered I wire from VCCIO to VCC, which converted everything to 5 volts.
The DTR line is used for the auto reset feature, if you don't care about that, then don't hook it up. Myself, I want everything to be as automatic as possible. Once everything is installed into the car I won't have easy access.
