Track Assassin

hooked up the safc on a sr, all the wires are right, start it, it died like 5 seconds later, the only thing i could think of its the maf wire. on the instrution from apexi i gotta cut the maf wire and splice them to a yellow wire and a white wire, i dont remember which wire goes to the ecu side and which goes to the maf side but i know i hook them up right. so i took out the white and yellow wires and hook the maf wire back together and it start fine. so right now the safc is more of a display. is the safc broken? or did i set the sensor wrong? the car is running stock sr maf.
