i bought a code reader from walmart and hooked it up when i try testing it the light just stays on i left it on for 5 minutes still nothin what could it be?
Did you turn the key on run? I have the same one, black and yellow sticker box with little red light and a beeper and a single and diferent group of prongs on top? The first time i hooked it up it was doing that and i was confused then i noticed i had the wrong single wire hookup to it. On my 87 there are the normal self diagnostic hookup and TWO single wire connectors. I had the wrong one hooked up, i think it was for the stock underhood light since now i have an aftermarket hood. One is black and the other is like a gray. Hope this helps.

Yea it comes out of the same harness, its a orangy color wire and a light grey connector. The one you dont want is a black connector and it comes out of a seperate harness so just make sure you use the one that comes out of the same harness as the big plug.
There is a large black connector which is psuedo prism shaped and a small grey square connector with a single wire they both need to be plugged in with the key off. Once they are in there, put the key to the run position and read away.

You may have some wiring problems. Use a DVM or Ohmmeter and measure the resistance between the black/white wire in the lage connector and battery ground. You should see less than .5 ohm.
Note that all resistance tests must be done with power off. Measuring resistance with a circuit powered on will give false readings and possibly damage the meter.
