factoids
the new EGR in hand works on both engine, CAL or fed in the FED car real and real fed ECU there is no wires, to connect on FED.
it is because CALIF did not allow then vacuum drop test for EGR tests, then, only heat rise from the thermal probe, Calif probe)
The CAT missing makes the EGR modulator dead and as a result the EGR main too is dead. EGR 100% all dead end to end.
this EGR is like famous Rube Goldberg exhibits wiki him ,funny guy from old days. and Fair grounds etc.
the sensor is REGTS named by suzuk, i call it EGR thermo probe to be more clear.
no part 14 on yours. only on(89/90)
FED uses MAP
CALIF uses CALIF only (labeled part) and Calif only ECU to match.
the #4 exhaust port is the CAT back pressure Port, about 0 to 2PSI max and EGR is modulated at that input. MAP is vacuum or baro sensor (manifold air pressure same)

the tests are complex and the injector of EGR gas paths can be a SUPER pain to clean and make work, so most now are DEAD.
