quick question, i have got a loom from a 2wd cossie that was in working order when removed, i am using it in a project of mine and today i started to wire it in and up to the engine, the only trouble is that i only have one coil wire coming out the loom the negative side green wire, i have checked my own 2wd cossie and it has a green negative wire and a black and yellow live wire, so i stripped the loom of all its insulation and the black and yellow wire is no where to be found, the only black and yellow wire that is there goes to the ign amp, can anyone shed any light on this and can i just tie into the black and yellow wire off the ign amp to run a live feed to the coil ?
