I have a 1995 Chev Blazer that is a OB1 system with a OB2 plug all sites including this one tell you how to reset the 12 pin ob1 95 Chev pin A+B
but that Blazer uses an OB2 bpug 16 pin shown above,There are connection on pin 2,4,5,9,13,16. I would realy like if someone that knows can tell me what pin I need to jumper to pin 5 without smoking my ECM. I am tired of going to the Dealers etc. That have the readers I bought an Innova Scan Tool 1340 OB1/OB2 was told that woud read the codes that was (BULL) 350.00 waisted!
thank you for your help
