My turbo kit came with a MAP (black box) for the throttle pressure sensor. My question is where does this little box wire up to? Does the throttle body harness have four wires? The box wants me to splice into the pressure signal wire, but it is not clear which one this is. The box also has a red (+12V) and a black (Ground) wire for me to hook up. Would this wire into the same harness?
Also, My 99' Impreza runs MAF not MAP... is this MAP box a "Map Computer" box? I'm rather confused. HEEEEELLPPPP!
