Okay I bought a 12 Pin ALDL OBD1 Bluetooth / Code Reader/ Scanner / Adapter from 1320ELECTRONICS and found out my 92 GMC Sonoma 4.3L V6 SLE has an EMC model 16144288 and searched with 2732a to find out that i need the definition file $A0 which happens to be another $19.95. I've already spent $75.99 on Bluetooth adapter $20.00 on ALDLDroid what else do i need to do or am i doing something wrong and please help because I'm stuck.
