read all of the instructions. you have to unbolt a panel to be able to get to it. it isn't going to be off of one of the plugs that's visible once you get the kick panel off. i think you have to remove like 3 bolts or something like that.

Ya thats what I did. After you take the kick panel off theres two bolts you have to remove that hold 3 plugs then once you move those out of the way theres one bolt that holds the main plug into the actual ECU the only problem is I dont know what color wire to tap into because my wire color doesnt match the wire color in those instructions. Could I get a tach reading off one of the wires to the coil pack?

i don't understand how you don't have that wire. and that wire is the COP tach signal wire. read those instructions carefully. it says that it's the COP signal wire.
