help on dumping codes 94 5.0

Are you trying to get rid of the stored codes?

You should just be able to disconnect the battery and let it sit for like 20 minutes or so...that should kill the memory codes...

I have heard that you have to touch the negative and positive leads together to accomplish this, but I have never had to...
 
Touching the leads together quickly discharges the capacitors (so one can reconnect the battery after a minute or less).
 
It might be easier to disconnect the battery and then turn on your headlight switch. You just need to create a draw (like the headlight circuit, brake light circuit, etc) to discharge those caps.
