So, my car has wires that are blue black red and white and new plug wires are black/yellow, red/white, blue/white and green/white. I'm pretty sure my guy wired them together wrong because my car now won't start it won't do anything sometimes it'll light up on the dash but it's not even making a noise when I try to turn it over anyways if he does happen to have them wired correctly, I will write out the long saga that is the current problem with my car. And it's long. Ugh. Anyways if anyone knows what color wire goes to what, do tell. Please and thanks
