If it is aftermarket:there are 2 plugs over your ignition coil on the left plug there is a white wire on the right plug is a black wire its one of those two. splice it spread the rubber apart wrap the green wire(tach lead) from the tach around the exposed wire like a T and tape it off. Black(-) wire to the negative of the battery and the red(+)...pull out the fuse for your wipers stick the wire in the fuse hole you should see the meter jump when you put the red(+) in the proper positive side of fuse hole stick the fuse back in pinching the red wire to hold it.There are 2 loops of wire on the back of the tach right? cut em both if its a 4 cylinder. tape em off so they don't touch. If its 6 cylinder you only gotta cut one, don't know which one it is thought you can figure the rest. that's how i did my 99 sunfire.
