Hi, I understand this is an old topic, but I'd like to suggest using FastLED for this, I've had much luck using FastLED's library for this model.
After reading the FastLED library setup your definitions like this:
#define NUM_LEDS 10
#define DATA_PIN 9 // whatever pin you connect the green wire to
#define LED_CHIPSET TM1803 // Radio shack's chipset (SKU 2760339)
#define COLOR_ORDER GBR; // Important for correct color naming.
Here's a link to my github, all of my projects are based off of the TM1803
