Jay;
        Good question. I have not tried this yet, but will since it
sounds like a good idea. How about removing the O2 sensor and finding an
"O" terminal that fits over the threaded part. Then crimp and solder a
ground wire. Screw all back in an ground to common spot on head.

Drive Safely & Good Luck
