Thanks for the response, trying to get the speedo working on 72 Blazer...Custom dash bezel out of 93 Caprice....Whole drive train is out of Caprice as well. I did get the pin out for the dash bezel, power to speedo and ground connected ...speedo input is not connected....A10 from ECM
is wired to the buffer module, any ideas where to connect speedo input wire?
