I know old thread I’m doing same build hopefully I’ll get to upload, I’m currently at the position where I’m not getting fuel to rail. Tested j17 relay (409) tested power supply to fuel pump and I was only getting 0.3 volts. I’ve followed both wiring grams bfq (1.6) and aug 1.8t). I believe the purple and white in 10pin orange plug needs to pair with the purple and white in 6 pin brown plug. \_(0.o)_/ I’ll try tomorrow…
