The tap shift doesn't change the shift indicator, as far as I know. The yellow wires on the C100 plug need to be aligned with each other. Look at the C100 plug and let us know whats there to begin with.

To the best of my knowledge, yes.

Go to alldatadiy.com, create an account (or if you have an autozone account, I think that works too? Autozone owns alldata I think. You can also see some diagrams inside autozone's website as well, but not as in-depth as alldata, but free), purchase both the suburban and duramax trucks, and compare diagrams between the two trucks.

To find the C100 plug for example, go to:


Vehicle » Diagrams » Connector Views » Connectors By Number » C100 - C199 » C100
