OBD 16pin to GM 12pin OBD1 OBD2 Connector 12 pin for GM
Miss leading add for this product !!!  They call it a adapter for OBD 2  To  OBD  1  But after you buy it, and get it, it will not work because they left out the part that your OBD 2 scanner must be able to read OBD 1 ??  There fore It is useless !!!!
