Hey Alll!

I had to tear out my heater core assembly on my 2019 Forester due to a cracked drain pan. To accomplish this I removed the dashboard and pretty much everything up to the fire wall. After changing the broken part I assembled everything and attempted to start the car, no start or crank.

Here are a few things I noticed:
  • Red led strip around ignition isn't lighting up
  • AC/ Heater doesn't turn on when in ACC mode
  • Engine not even trying to crank
yes, I had battery disconnected the whole time I was disassembling and assembling the car.

I hade some leftover connectors I cant seem to figure out where they go. I have a premium model so maybe they're for some module I don't have installed? or maybe this is contributing to the issue?

Please see photo of connector below. Any help is appreciated!
