Hello,

Here is the hookup....

To extract DTCs from the computer for diagnostic purposes, the Self Test connector is used.

Start engine and bring to normal operating temperature. If engine will not start or stalls after starting, proceed with next step.
Turn the key "OFF", then wait ten seconds.
Activate the self test by grounding the Self-Test Input (STI) connector.
Turn the ignition key "ON".
Record all codes received.
Turn ignition "OFF".
