The above site lists Ford trouble codes. You might find it useful if you use the following diagnostic trick:

With the key OFF, push (and hold down) the SELECT/RESET button on your odometer.

Start the vehicle while still holding the button. Continue to hold it down, until all of your gauges jump up to their maximum, and then return to normal.

When you see "bulb" in the digital odometer readout, let off the button. This is the gauge test mode.

Some of the things you can view on your odometer screen are:

Digital speedometer (mph)
Digital tachometer (RPM)
Digital speedometer (kph)
Battery Voltage
Engine Temperature
Plus, you can also view any TCs stored in the computer!
I've previously done this before because i had heard of it and thought i'd see if it worked. its fun to play around with the tach and mph. it keeps me entertained while driving.

Ok so if I'm reading this right I need to make sure my truck is up to operating temperature first of all. After that hook up the wires like stated, then go back to the cab and turn on the key and be ready to jot the flashes down, correct? The truck I'll be pulling the check engine codes from will be a 91 F-150.

Yes, for the KOEO (key on, engine off) test. Follow the additional instructions for the engine running test.

I cant get the digital thing to work nor can I do the engine light test. The light just stays on

When I do the digital readout thing it just say "E03" and if I press select it goes into "972CAL" and stays there

thanks for posting that! very helpful...however it did not work for me...I have a 93 F150 with a digital mileage. separate select and reset buttons if that makes a difference...tried to hold down both, or one or the other and neither way worked... gauges never moved, bulb never showed up.

I can not get my 95 to give me any codes I ran the jumper wire from the one connector to the top right connection of the other house connector. then I ran A wire from the house connector on the bottom row second one from the right as the picture shows to the trucks positive battery lead. The only thing that happens is my check engine light comes on even with the key off. when i turn the key on the light goes out and nothing happens? am I doing something wrong?

On your '95 you only have to run the jumper wire from the single connector to the other connector on the house looking plug. The additional wires are for trucks that don't have a check engine light, like my '87. And even then you don't hook that terminal to the positive, you hook it to the negative of a voltmeter and the positive of the voltmeter to the battery.
