Default 08 STI AP Connection Issue

About a year ago I picked up an Accessport brand new and flash the car to a Stage 1 tune, and would monitor using the AP on and off but wasn't driving the car much. Fast forward to now I decided to do some monitoring and when I plugged in the AP - it was stuck in the "Verify ignition is in the ON position"

I've checked all the fuses and probed the OBD2 port and everything seems to be in working order.

I also talked to Cobb and sent them the AP and OBD2 cable which they tested and sent back and said there wasn't any issues. When they sent it back they forgot to upload the backup data so now I have an unmarried AP I guess if I decide to just sell it?

I have also tried a different OBD2 cable (brand new)

The only things I can think of that happened between when I knew the accessport worked and when it didn't is that at one point, my battery died completely from sitting and driving short trips, I set it up on a trickle charger over night and has since been reading 12v or higher and at one point my stereo completely turned off, but then came back a minute or two later on its own.

I did use the AP about a week before my battery died. I can check IM readiness and I can also view the identity of the car, so I think its able to communicate with the ECU?

Anyone have any suggestions?

Battery Voltage is fine, with the alternator disconnected is fine underload as well. Reading 14v + w/ alt connected. I went through the obd2 port with a multimeter again, and it looks like pin 7 for the K - Line is reading 0V, but is acting as a ground - pin 7 and pin 16 showing 12v for the battery, so I think theres a short somewhere on that wire

After running a new wire from the ECU for pin 7 on the OBD2 port, everything works!
