OK, So i have an OBD2B to OBD2A jumper harness and it works great but the tach doesn't work. Does anybody have an OBD2B to OBD2A jumper that can look at it for me and let me know if there is a resistor in there that isn't in mine or two wires into one. something like that. mine goes from one connector to another no spliced wires or anything like that.. Any help would be appreciated and thank you in advance..
