Hello, I recently purchased a 06' si and its been great! When I bought the car it came with a non working tach, so I decided to order a new one that came from a 08' si. After installing the tach it gave me a tmps light (probably cant turn off since the car has no tmps relays) but the airbag came on and has stayed on, I'm not sure how to turn it off. Any help would be appreciated, thank you!
