Okay, I'm ready to install the brain in my car. The first task I'm going to handle is my steering wheel controls. My model (4th gen Camaro) is 1-wire resistive. I have a diagram of the pins.

C3 - White 10-pin connector
11 - GRAY - (Convertible) amplifier sensor
12 - not used
13 - not used
14 - DARK BLUE - steering wheel controls input
15 - not used
16 - DARK GREEN w/WHITE - (Camaro) vehicle speed sensor input for automatic volume
17 - LIGHT BLUE - right rear speaker negative
18 - DARK BLUE - right rear speaker positive
19 - YELLOW - left rear speaker negative
20 - BROWN - left rear speaker positive
*Note* That info came from ls1tech.com I don't take any credit for it

.
So I have one wire (wire 14 on the diagram) that inputs all of my information from my steering wheel. I have two issues.
1. How do I physically hook that wire up to the analog pins of the brain?
2. Once it is hooked up, what do I have to set in the software to make it convert the resistances to roadrunner commands?
