Im sure its been covered here before but all the surching ive done hasnt turned up much information, i have a 1993 geo tracker and need the ecu pin out diagram, in order to install a mixture meter i need to know which pins are which.  Any help would be appreciated.

If its an 8V then there is a copy of the ECU circuitry showing pinouts on my website. You need to look under Schematics, yours will probably be the same as the one in the Vehicle Installation Drawing, Japanese TBI model.
