s4 turbo engine/ecu into s5 vert problems

Ive used the search function and yes I know t his isnt the best route to go. Ive tried doing a repin/bridge per the FSM but I cant figure it out. the fuel pump isnt coming on, the leading coils arent firing and the secondaries seem like they are firing half the time they should be? is there another post I can look at that has a write up or something similar?

would it be easier to make an entirely new harness that runs to the CAS, trailing coils, and leading coils and just skip the inside harness all together?

only productive answers please, no flames. im way too tired.

read the pinouts and the wiring diagrams.

making a new harness will result in all sorts of shielding/electrical noise issues.

Nobody can tell you what is wrong, because we've no idea what you've bypassed/repinned/worked around. We've no way to check your work out from here. Can't be done.
