Rich Posted February 4, 2003 Share Posted February 4, 2003 Looking at fitting a rev counter today. I have been told to fit the signal wire to the + on the ignition coil arrowed. The coil and the wiring diagrams do not indicate what wire is the positive. does anyone have any clue?? Also in the passenger footwell is a socket and a silver box, any suggestions what the port is, we think the box is the engine management system is there a diagnostic port in the escort that i can connect the rev counter too??
