the tips were on it when i got the car, i guess the guy i got it from works for ford so he stole them from work lol and the check engine is for emissions, im guessing because of the high flow cats, SRS is because the fuse for the air bags is blown, just havent gotten around to putting a new one in lol and abs and tcs are both on. probably going to be fixing that next weekend since its my first weekend off in a couple months!!
