Hello,
I am preparing for a swap in my 2006 Colorado with a 4cyl 2wd manual trans. Using a 2003 suburban 5.3.
Would you be able to share the pin outs to get the gauges and everything in the truck working?

Welcome to the Nation.

As you probably already know, 95% of the functions of the instrument cluster are controlled by the Serial Data Bus. Getting that up and operating will be a requirement. I sent you a message.
