so i wired my injectors and im not really sure what to do with the dedicated +12V(gray/red) wire. the instructions say to split it between the 4 injectors. but if i were to splice the wire and split it 4 ways, wont that reduce the flow of current? or am i an idiot and doing it wrong?

 

No the trigger is a Negative signal. Your talking small amounts of power to drive the injector. just make sure you make solid conections and you will never see a problem.

 

alright thanks man.
