I have an OTC enhanced monitor that I bought to use on my TPI but now I also have a 97 vortec truck that I will be doing some programing on. I have the cable that plugs into the ALDL for the OBD II and a smart insert but it won't read the engin it seys I need part # 3305-73 or 3306-01 are both these smart insert part #s? does anybody know where to find these?
Thanks in advance
Kevin
