    on the 93 Probe ATX MECS controls are used; it is called EEC instead of EEC4.
    There is a small 2 X 2 black box to the right of the battery: this is the diagnostics terminal box. You want to make up a short wire jumper (preferably 22 guage single strand wire but it can be any guage wire), next, connect terminals TEN and GRD in the box. (ten is the 3rd terminal over on the top row...ground is the 1st terminal in the second row)
    After the jumper is in place turn the ignition key to the on position, but do not start up the engine.
    Next look at the check engine light (CEL) located right below the speedometer - the CEL will begin flashing if there are any trouble codes stored in the computer. If no codes are stored the CEL wont even turn on.
    An example would be: 2 quick flashes followed by a couple second pause followed by 3 more quick flashes would be code 23..there may be more than one code stored so be sure to watch the complete flash sequence at least twice and then write down the code numbers..check out performance probe.com to find out what a particular code means
