No Light?
The most likely problem is the cable. Unplug the cable and test each wire end to end for continuality (you may need to use paper clips or fire wires at each end). Also carefully inspect the cable for any cuts in the insulation. If everything looks OK, then check the solder joints on the connector on the ECU (if the ECU has run with Hondata before then it probably is OK). If everything on the ECU looks OK then call us and arrange to send the s200 in.
