Injector Question
 

My injector's arent firing, so i know the problem is the wiring cuz i made the harness, but there are two wires that go to the injector the light green and whatever and the black and yellow, now the black and yellow i did wrong so i was wondering can i take the same black and yellow wire that goes to the injectors from the main relay and splice into the main relay and just run 4 wires from there to each injector...? if anyone understand me please help me out, and if you need me to elaborate lemme know...

thanx

anybody...???
