Any chance the LS1 will be updated anytime soon? There isn't a full wiring diagram anywhere (that I can find) and it's tough if you step away for awhile to figure out what you've already done. Am I missing something?

We do not publish our chassis or fuel injection wire diagrams. The harness should have printed section labels on all connectors and open ended wires. Just connect them as labeled and if you have specific questions about any connection feel free to ask.

There is a pink/black wire that is grouped with the DLC connector...does it need 12V on start/run and that's it? What color is the Check Engine Light wire? Brown? Brown/white? Does it just need a chassis ground to complete the circuit or does it need power and the brown/white is a ground?

Chris,

Pink is Ign Hot only.

Pink/Black is the power source for the check engine light.
Brn/White is the ground source for the check engine light.

Your ECM was flashed and shipped last week.
