My 92' N/T injector wires
4 thick yellow wires = ground
2 thin pail green & 2 thin yellow = power from ECU
resistor wires = white & 4 black

So I cut all four thick yellow grounds, attach the white resistor wire to one of the thick yellow grd wires that RETURN to the firewall.
now I will attach the four black resistor wires to the thick yellow grounds that are coming FROM the injectors.
I think I'm still lost here?
