I had just assumed that I had a speedometer cable since I had an analog speedometer dial. Also I have a Ford Service Manual on CD ROM which refers to a speedometer cable. But I looked under the car today and I DO NOT have a cable. Just a connector on top of the speed sensor with 3 wires coming out of it. So I guess I have 2 choices - change the speedometer gear or buy a chip? And that's if I can find a gear. How do you remove the gear? I saw a roll pin on the speedometer gear housing. It looks like you have to pull it out with vice grips? How much benefit is there to buying a chip? Does anyone have any documented performance gains? How much does gas mileage suffer? Thanks for all your help guys.
