The E1 pin in the diagnostic port is also Ground. So if you had the proper Toyota SST (09843-18020) that has three connections it should be easy.
Well I made my own SST with three pins (bored); tested for continuity; but the damn switching of pins is very frustrating. I've tried about twice a year for the past 4+ years the light has been on. The bulb may burn out before I get this!
