Hi I Am Going to change on my 325 and I really don't know what is the extra line that my spark plug cable set has its a thin line with a square piece at the end. Someone Knows what it is And where it Goes??
well im not certain so it may pay to double check or wait for someone else to chime in, but i think its part of the pulse sensor system, does it have a plug on the end of it? if so im pretty sure it connects to the plug beside the plug for the pulse sensor (which is underneath the diagnostic plug by the oil dipstick)
