Its emission time for my car and Im having a dilemma on what to do wiring wise. My car had a 98 itr motor in it which didn't have a chance in hell of passing smog so I swapped it out with a friends vx motor he had sitting in his garage. The problem is Im not sure what to do wiring wise due to the cars wiring setup. The car is a 95 cx that had its stock interior harness pretty much changed into an obd2 harness and Im not sure its going to fly with the stock vx harness. Would I run my odb2 teg harness and switch out the motors o2 and run a p28, try to get my power fc to run the vx and lean the **** out of the base program, or do I need to do something completely different?
