I need help finding the tach wire on my 98 cavalier. I have searched high and I have searched low, I have asked GM, I have looked through the Hynes manuel (in which they showed one but not the location or color). I have been all over the car. But I know it is there, somewhere. So if anyone can help me i sure could use it. Thanks

all you have to do is go to the #1 injectore test both wires on one should read like 14 volts & the other should rise & lower with the rpm stop looking for tach this is the 2002 way

Go to the uncommon injector wire if you can not find the WHITE or PURPLE / WHITE wire located at the engine harness which is found next to the battery, below the radiator hose, just above the transaxle.
