top one should be you iacv..bottom should be your tps. also, i have one of those bluetooth odb II adaptors and i always unplug it at night, the ecu is still giving it power with the car off so if your battery isnt so great that does contribute drainage.
you can get self heating o2 sensors super cheap online, also if yours is a manual trans id get a tach, obd adapter does it but its nice having a real guage..
p.s. love the homemade flaps i may just do that myself
