I just installed a turbo timer, S-AFC, and a 2nd turbo and the first time i turned the car on i got the check engine light, the airbag light, and the trac off light to come on. My trac fuse is not pulled, btw. I know that the instructions to clear the airbag thing is on the mkiv faq, but it is currently down, and i'm not sure about the others. Any help would be appreciated. Thanks.
