I have a '86 K5 Blazer. supposedly, that was the year that they experimented with emissions control. i have a box above my glovebox that seems to be like an ECU, but it's supposed to be "emissions Control" first, i have heard that you can bypass this box by crossing wires, but i dont know which ones to cross. second, i would like to find out a gm part number or somewhere where i can buy a new one. any info you may have on this control box would e extremely appreciated and helpful. Thank You
