I have switch in the wire that supplies 12v to the fuel injectors and it works great. ON most cars all the fuel injectors are supplied 12v by one wire and then the ECU grounds the other injector wires individually to open them.

edited to spell out that the ECU grounds the other injector wire, not the 12v one.
