So I had a bench setup made from BOTH ecu connectors and a obd harness acouple years ago that worked flawlessly. Now I cant find it anywhere so I pulled another set recently to make up another one.

The problem im having now is I cant remember which pin on the smaller ecu connector (#82-121) gets power as that was the solution to the same problem I had b4 when it worked? anybody know?

I read thru the sticky on bench flashing. Just cant remember what thread tip me off to that pin back then when it worked

That’s what I was thinking too, it’s just non existent on the harness I pulled from an a6 that threw me off but I’ll try that and re pin it somehow if it works. Thanks
