figured it out, basically, the nissan T-harness is garbage. i regret buying it, and i should've just wired it all manually. theres no configuration that sends the correct signals to the correct wires. I had to modify the T-harness and solder the purple and orange wires together. because the orange accessory wire goes to an empty pin, and it's the purple one that goes to accessory, but i have to keep the purple one in tact as well in order to retain the normal key forward use of accessory power. so yeah, in my case, 2004 nissan 350z with the trash thar-nis2 harness, i had to splice into the purple wire (accessory pin on the ignition switch), and join it anywhere with the orange wire (accessory pin on the evo-one harness). and now i have remote start along with accessory power, good old remote start AC finally, and head unit, and well, all accessory power.
