To clear the ABS computer's error codes I've read to connect the GND and TBS terminals in the Diagnostic box. See if you can find this mysterious port in the pic below.

 

That's right next to the fuse block by the battery.

 

I know where the diagnostic box is, i took that picture, but I took it to show that there is no "TBS" port in the box, at least not mine

where can i find the TBS port so I can reset my ABS error codes?

 

I don't believe there's any diagnostic port for the ABS system. I checked my shop manual (Section P) and the system is pretty simple. The ABS control unit is in the hatch - inputs are the wheel speed sensors, and output is the ABS pump and the "ABS" light in the dash.

If you have an ABS light due to a code, try disconnecting the negative battery terminal, holding the brake pedal down for 10 seconds or so, then reconnecting.

The only electrical test procedure outlined in the shop manual is with the special Mazda tool.

I believe the most common problems with the ABS system are in the wheel speed sensors. Visually inspect all of them, make sure there isn't crud on them keeping them from taking a reading, and make sure the wiring to the sensors isn't damaged.

just found out that port isn't on 93's, only on later cars. I'm pretty sure my light is on just because of a stored error code from when my ABS sensor wire was severed (the whole sensor has since been replaced and the brakes bled). I'll try resetting by pulling the fuse for a while, and then with the battery if needed. I'll let you guys know.

 

Reset the ABS computer like you would the engine computer: disconnect battery & press the brake for a while.

 

any indication when it was been reset? how long do you typically hold the brake down?

 

Sorry, I misread your question. Like DaleClark said disconnecting the battery and holding the brake down should clear out any error codes.
