dumb question because the thread is about connecting 1g tt ecu to 2g harness. But would this work the same if i wanted to use my 2g harness and connect a 95 hybrid tt obdii ecu to it? I goofed up and bought a 99 ecu/harness and now have just learned about its ability to relearn quickly; thus, not allowing me to keep my tune. There's always something you learn while doing the tt conversion ...ah if i could do it over again i could save so much money
However, if i could use my na harness with an obdII ecu, would i pass emissions? Damn the enviroment!!! HAHA. Another idea, could i use the 99 harness and plug up a 91-93 ecu since its 3 plug as well? Worst comes to worst i could just disconnect the 02's so i can keep my tune with the 99 ecu, supposedly this works.
