EGR/SAI Delete: Any Wiring Issues?

I'm back after a long hiatus/family health issue. Starting to get my rebuilt 2uz back up and running.

I've done several new things after getting the motor back. Added a Link ECU, installed my headers, upgraded the fuel injectors, etc. One of the things I did this time was delete all the Secondary Air Injection equipment. Can't believe how much easier it is to work on this thing now. Takes 20 minutes to pop off the intake manifold instead of hours. Yay.

One question I haven't been able to find much discussion on is complete deletion of SAI pump/valve/sensor wiring. Has anyone done this successfully--either by programming the ECM, intercepting the DTM codes with the secondary ECU, or putting a simulator on the circuit?
