New build no ignition power

So I just redid my entire engine bay and Im ready to fire up my new engine. I have no ignition power. No chime when I insert the key and no power on the pink wires to the ECM. What did I do? I have power on the Hots and power at the blower box reds. What did I miss? All wiring from engine bay was removed for paint. I have a dome light and dash lights work. I did not wire in the front headlight harness yet.

Sounds like one of the fusible links at the starter isn't hooked up, or has failed. One works, the other does not.

I found it.. I think I had a loose connection at the firewall bulkhead connector. I pulled it off to check pins and all is good now..
