Checking Codes with a paperclip?
Hi all,
I got a '93 F-150 with a 300. Can someone explain how to check the codes with a paperclip? I knew how to do it on my old car but the ports are different on this. My old one had two rowsof ports this one has one. I tried searching but nothing useful came up.
Also, I dont have a Hayne's or Chilton's manual so can someone tell me or give a link to what all the codes mean? I'm not having any problems (knock on wood) but i would like to know how for any future mishaps.
Thanks in advance!

No those are not the ports you use for pulling codes. Sorry I just checked the link that I posted earlier and that is for the KOER test. No wonder you're confused 
Here's the correct page:

That should clear up the confusion.

So the only part I have to do is put a wire from the STI to the Neg. battery terminal then? And turn key to on and read the codes that flash, right? I just want to make sure I completely understand before I go and do it. Dont wanna screw something up, you know?
Just out of curiousity, what ARE those ports under the dash for? Im used to my '67 F-100, so I never had to deal with computer stuff.

Yes it appears that way. I've never done it the manual way, I use a $30 code reader.

I did. And if you'll notice steps 1 and 2 were cut off for some reason. Step 2 and 3 seem to go together to me. Just wanted to make sure that was all. It shows a picture of another plug with the STO, SIG-RTN and fuel pump and I wasnt sure if that applied or not. I aploogize for being newbie to engine computer stuff and not knowing what every abbreviation stands for.

Then I read it again and as you said, it appears that they repeat the same step twice!! WTF?! Lol. Anywho, Here's another tutorial that shows you must actually jump the #2 pin to the STI.

This sounds more accurate since most people say this test can be done with a paper clip. Good luck dude.

You can pick up a cheap OBD-I code reader at most local auto parts stores. Here's the one I have and it works great:
