Water Leak behind water intake

[Agoodwell]

Hello all, I was hoping someone could h lp me out. I fixed the pex elbows and everything behind my 6-1 water utility area. My problem is now i dont know what pex line goes where. I have a 28bhs and can only trace the pex lines so far. There is 5 total hook ups. 1 obviously is the hot water line for faucet/outdoor shower The other 4 are the cold water for faucet/outdoor shower, city fill, tank fill, and the flush line. 3 of my blue pex lines had elbow connections 1 has a straight in connection. 1 of the blue pex elbow connects had red tap around the end. I made the mistake of not taking a pic beforehand. Can someone direct me to correct connections or take a picture of theirs. Again this is easy to get to, it is under the lower bunk and behind one of those cheap hide away panels.

Any help would greatly be appreciated
