scanner port again

This truck does have a scan port and it is NOT on the drivers side by the brake booster it IS on the passenger side hanging loosely on the firewall.Really doesn't even look like a port,but a connector that might plug into something that isn't. The other post re: not even needing a scan tool is accurate,since turning the key on and off three time then leaviing it on will cause the check engine light to flash the codes,thus doing the same thing that the tool I have does for free.

The information I have shows the diagnostic port connector near the brake booster in the engine compartment.

the last i knew the 93 didnt have a scan tool place u turn the key on and off 3 times and watch the check engine light it will tell u the codes for more info e-mail me at hot_rod_355@yaho.com thanks chris
