ok on the main engine harness in the module/coilpack area.

look were the wires come out of the big conduit and there is a green plug with nothing plugged into it and it has 2 white wires going into the plug.

With my tach I used a splice connector and spliced the white wire. Look at the coilpack and count 4 from the right and there's your signal.
