Wiring harness redux

[c-rad]

So I have an auto harness, and I want to eliminate a lot of the non-essential plugs. Stuff such as the dropping resistor, stock boost control solenoid plug, and the ABS plug. Can I just chop off these plugs and tuck away the excess wire? I assume I can seeing as the manual ECU won't be looking for them...(aside from the stock boost control solenoid plug, but I cant imagine the ECU throwing a code for it). I can post pics on request...
