Help: Steaks!

SocialiteFashion will be doing her FINAL grill this Sunday! I have one question: I bought 2 organic strip steaks — how long should I marinate the steaks for if I’m using pineapple juice, along with soy sauce, red & white wine, garlic and onion?  I’ve already purred the mix, and the meat is currently soaking in the marinade —- is 24 hours good? or is it WAY too long?
