CHeck engine light has been on and I took it to a local dealer (non-Moomba/Supra) to read the code. the sensor tells the pcm the boost pressure to modify fuel delivery, gear ratios, etc. dojo.addOnLoad(function() { HI , Its a resistor that replaces the oxygen sensor (i think), so the cat converter is bypassed. The second is the boost sensor: Fools the ECM into thinking boost is higher than it actually is. Details about 2482162 Turbocharger Boost Sensor Gp Pressure For Caterpillar CAT 274-6717. Figure 6-14 shows the location of EMS components on the C-10 and C-12 engines. And I think I might've found the sweet spot; there's no pending code and both oxygen sensor monitors are OK now, so I think it passed its tests. I was told it was throwing an active code for the post catalytic oxygen sensor on both sides. An interrupter harness is just a male/ female shunt harness with a resistor in it to keep it from going over a certain return, hence making it a "code blocker" or "fooler".
