jb4 c300 Brown patch error codes location of connections?
 

i been tinkering with this for about a month but im still gettting error code , before when i did not have the brown patch plugged, im not getting underboost anymore but im getting the following error codes and tbh it doesnt feel much fast or faster at all, , i just wanna double check if iput the sensor in the right place, if not where is it ?

error codes
p2003 and p0106 and p0000

Attach a JB4 log, I can see if the psi2 signal looks correct.
