So what your saying is that i could use a 99-00 civic manual harness and ecu and it would work perfectly, or i could use a harness from either an obd2a or an obd2b teg, and use the ecu from an obd2b teg, and it would work perfectly? Im not going to have to add any wires either way or manage to screw up the wiring as i probably would with changing around my harness for the JDM engine? How much do you want for the ecu, and you dont happen to have a harness just laying around do you? I dont need to pass smog, i dont think michigan gives a shit about that, but is the pt2 obd2a or obd2b? Will it still work even if say i have an obd2a harness and an obd2b ecu, both from an si? Im just wondering if i have to do any extra work if using the harness and ecu from a different car (si harness/ecu with gsr motor). Should the JDM shift linkage fit well also? And i do really need to weld a sheet metal mount for the manual shifter? And is it true that i can use the parts i need (pedals, shifter, MC, Slave C, hydraulic line from MC to Slave C, etc) from any civic or integra?
