Where do these wires go???

The right 2 wires... They are the k-line and l-line used to reflash the ECU. I thought they would go to the OBD2 port as there is an orange wire that goes to that plug but I tried my software on the car and it was a no-go. Is there anyway someone could pop apart their ECU plug (it's just a zip-tie that needs to be removed and see what colour the wires are? They are not documented in the hyundai FSM but maybe the colours are listed somewhere. First trick to to verify that there is a wire in each position (fairly sure there is).

I thought pin 15 would go to the OBD2 plug. By the photo you posted it does not look like it but someone on gencoupe posted a photo of his obd2 plug and it looked like it did :( Is there a way you can pop the plastic piece off the ECU connector and get a photo so I can see all the wire colours? Indeed it is the 3 yellow wires on my bench harness.

The pins your are using are this:

76 - no info on the Hyundai PDF
77 -CAN [High] Other control module, Data Link Connector (DLC),
Multi-Purpose Check Connector
78 - CAN [Low] Other control module, Data Link Connector (DLC),
Multi-Purpose Check Connector

So they should go to Pins 6 and 14 on the OBD2

Also looking at the PA OBD2 reflash module the pins 7 and 15 are also used...I suppose the K line is the pin 76 on the ECU/pin 7 on the OBD2..

Based on your pic, I see (sorta black) red, blue going from right to left. I am indeed wondering where the Kline and Llines go. These wires are required for the reflash.

Well...they should go to the correspondent pin on the obd2...

But you are only using kline...because the other 2 are can high/low...
