My first impression is that anyone who is probing ECU wiring should be able to tell me where X11/4 is.

X11/4 is the 38pin diagnostic connector and it is under the oil cap looking cap on the electrical center at the right side hood hinge area.

Just what would you like to do with the engine speed signal "TN"?
