Currently prepping the car for boost and decided to remove the egr crossover pipe to to exhaust manifold as well as the valve on the intake manifold. I blocked all the ports off but I was curious if I can throw these wiring modules in the trash?
I will be installing a MS.

 

with a MS as ECU the answer is yes. I have done just that.

 

I can confirm that these aren't necessary with a standalone.
