Not getting power to the ignition.

This is for a 1973 Dodge Dart Sport. For starters,I’m a novice with electrical. I took apart my dash a few weeks ago to give it a refresh. I took decent pictures and took note of anything that might trip me up when reassembling. After reassembling the cluster bezel and installing it, I’m not getting power to the ignition and it won’t start. It’s just dead. The bezel is getting power, but when I try and start the car, there’s nothing. The rest of the dash... radio, A/C and what not hasn’t been reinstalled. It has an aftermarket wiring harness that the previous owner had installed. Does everything have to be reconnected to the harness for the ignition to work? I don’t want to fully reassemble the dash if I have to go back in there to figure out other possible failures. Any help is appreciated.
