Default JB4 install error - 07-19-2019, 01:42 PM

Hello. I'm fairly sure I've attached the various cables correctly but when I turn the car on in ACC mode, I'm getting a warning about RPM > 3500. The car isn't running so something is strange. If a disconnect the JB4 from the fuel pressure sensor and connect the fuel pressure cable directly back to the car, the error goes away.

All of my connections line up with the install doc, so I'm not sure where I went wrong or what to look at next. The car runs and idles fine if MAP and TAP are attached to the JB4 but the fuel pressure sensor is directly attached to the car.

Here's my connections to verify. Apologies if a few of these are rotated incorrectly.

BCM- not currently connected but is the correct? Cound't find any docs but went off this youtube video - JB4 Audi B9 S4, RS3, TTRS BCM Install Preview - YouTube
