Default 2005 2.5rs ej20 jdm swap obd2 connection

Hey, guys new to the forums so I've been searching for something that relates to my current issue and was wondering if anyone can help me, I recently purchased a used Subaru 2.5rs that has an 03 wrx engine swap in it after pulling down the dash because I noticed a few loose wires I came to find that the backing retainer for the obd2 port was missing and one of the wires connected to it went to nothing does anyone have any idea what the pins order should be and what color wires should go where?

Buy a bulkhead harbess 90% should hook up for about 250$ i bought a jdm ej205bwith avcs and i wanted the avcs.. So i bought a harness for my outback sport swap mostly everything hooks up a few grounds the ignition wires were so close to being identical have to pull those off the old harness .. Fuel pump wires pedel grounds ignition plug wires pretty much went a together still working on the fuel pump controller since the na 2.5 just came with a regular set of connector wires turbo charged engine has this controller set up .. If anybody knows anything about how to merge the controller i could use it!

Just my two cents I would use heat shrink tubing instead of electrical tape just remember to put it on the wires before you solder
