interesting. when I put these on, there was no tps on them, which I didn't care one way or the other, but when I drove out on them for the last 3 days the light didn't come on. odd i think. This afternoon I installed the lit doorsills from KPI and when I turn the car on the tps light is on? That's really odd to me, because even if I'd tapped on the TPS wire in the harness behind the seat, which I don't think is there then the tps doesn't go on with the door open and off with it closed as do the lights. weird huh???
