Like I said, it runs fine with it unplugged... Thank you for the quick reply and happy 4th.
If its triggering without the JB4 present then something else is at play. Try reseat the connection that is on the boost sensor on the intake manifold making sure you use the locking tab. Also reseat plug C on the side of the manifold as that one is for the fuel pressure fault.
