I'm with you: Wait for a time when you can work unrushed and with enough light that you don't make incorrect connections. It will also allow time for the equipment to acclimate to your room's temperature.
You can also use the opportunity to perhaps do a few things you've been putting off like cleaning and dusting, rerouting those cables and retightening connectors. And when it's all done and sounding great, you can bask in the glow of a job well done.
Happy listening!
