Can anyone give me some advice, i need to find which negative wire connects the coil packs to the ecu. each coil pack has two wires and on each of them the second wire is yellow (negative) , but when i look at the ecu there are five differant yellow wires that connect to it and none of which match the ones off the coil packs. Does anyone know which yellow wire on the ecu that is the negative froms all the coil packs

the yellow that goes to all the coilpacks is positive.
