I tried to search on here but got conflicting results. Anyone know the Left Rear and Right Rear +/- speaker wire colors for the new F150 Supercrew?

Or is there a website where I can look this up for free?

I'm using the speaking level inputs on my MTX amp to run my sub (since I'm still using my factory headunit). I want to tap into the rear speaker wires for my input. I hope to find them along the door sill somewhere instead of having to remove my rear door panels. Will I be able to easily find them along the door sill, or should I go to the back of the head unit and tap in there?

thanks,
Steve
