pass side behind dash. Take off the knee pad below the dash, the screws to get to it are behind it. It's mounted straight up on the right side

the ecm may be black if its remanufactured usually not painted aluminum it has two 7mm screws holding its mounting bracket it it mounted horizontal between the passenger dash speaker and dash support brace.
