That computer in your picture is the ABS computer(on the pass fenderwell), dont mess with that. If u do have a 96 then u should have OBD2 emissions system so you should be able to get a computer programmer from Hypertech or JET right? The Government mandated OBD2 so that repair centers could use the same scanners to read codes in 96 and newer domestic vehicles no matter what the make. They also have 2 oxygen sensors, one in front of the cat and one behind. My 95 has only one in the manifold, if u only have one then u have OBD1 emissions for 95 and older vehicles, then a 95 chip should plug in. If u have a oxy sensor behind the cat then it has OBD2 emissions and u should br able to get a comp. programmer. They are availble for alot of 96 and newer cars and trucks. Its almost the same as the $10,000 DRB2 scanner at my work. U can change rev limiter, spark and fuel curve, recalibrate the speedo and amost anything.
