Bought a 2000 civic ex and the auto tranny was swapped for a manual, it runs fine but I am get several OBD codes preventing me from passing smog test here In so. California. The car still has the auto ECU in it. Codes P1706 (neutral safety switch) P1768(linear solenoid) P1753 (lock up solenoid). There is no clutch pedal safety switch, they just combined the two large blk wires to the auto shift plug together making the car think it's in park. What do I need to do to rid my self of these codes and pass smog test, should I replace the ECU with a manual ECU and if I do, should I also replace the engine and dash wire harnesses or is there an easier way. can the ECU be reporgramed from a auto to manual and elemenate the P1768 & P1753 since the manual does not have these.

I know when I used an auto ex harness for my manual GSR swap, I had to do the 3 wire to 2 wire conversion for our IACV.
