Heres the post lucky37 posted when I needed to pull codes.I used a paper clip to jump from plug to plug.worked for me.hope it helps. """Here's how to read the codes using your check engine light (CEL). I'll describe the basic KOEO (Key On Engine Off) test:
First you'll need a piece of wire of some sorts to connect two terminals. You'll see what I mean.
With the engine off, pop the hood and find the EEC connecter, located on the left-hand fender closer to the firewall at the top edge of the engine compartment. It is a black connector not connected to anything, but it is clipped in a protective plastic piece. Unclip that connector (has 6 terminals) from the protective plastic piece.
Next to that connector is a small gray single connector in the same protective plastic piece. Unclip that as well.
Now looking at the larger connector with 6 terminals, oriented so that the 4-terminal row is facing down and 2-terminal row is facing up, stick the connecting wire into the top right terminal (right terminal of the 2-terminal row, oriented like I described). Stick the other end of the wire into the single gray connector.
Now turn the key to run (not to start) and read the codes. They will flash fairly quickly so get ready to write. How do you read them? I'll use 212 as an example: it will flash once, followed by a 1/2 second pause, then flash again to indicate "2", then a 2 second pause, then it will flash once to indicate "1", then a 2 second pause, then it will flash once with a 1/2 second pause, then again to indicate "2". There will be a 4 second pause in between codes.
When the KOEO codes are complete, there will be a 6 second pause, then a single flash, followed by a 6 second pause. Following the KOEO codes there will be "Continuous Codes" displayed in the same way as above.
If you want to clear the codes, simply unplug the jumper wire while the test is going on.
So that's how you do the basic KOEO test to get your codes."""
