Can you label your wires for us?

I tried it using my xprog 5.1.1 with the wires that in_tech had posted up.. Only found one device for 9s12 device with external memory and it had 2 extra wires shown that weren't labelled in in-techs pics.. Didn't work, lol..

I think I may have jumped the gun on trying to read my bricked unit anyways.. Xprog goes to the main cpu and gets the memory by asking the main cpu nicely for it.. Since mine is bricked and the main ecu is running I am guessing this method will not work for mine..

Not really looking forward to soldering 80 wires like Tazzi did.. That takes skills and bravery I am lacking, lmao.. I don't mind ruining this one, but I don't have another one I want to loose..

WOOHOO!
Hello! Very interesting method. I have several E38 with wrong OS flashed, they work but you can`t do anything with it. I will try your method to reflash them.
