Congrats. Sucks they did not mark the wires for you when they disconnected the batteries, @Wylie_Tunes would know. You will probably have to post up some pics tho.
My boat did not come with bow filler either and I could not find a used one. I ended up making my own. Used cardboard to make the template so I could get it perfect (mine curved slightly on sides)....then ordered a piece of HDPE online at Interstate Plastics, traced template on it with sharpie and cut it out....and then had my local upholstery shop provide and install the foam and vinyl.
Not sure how far back Fineline keeps templates and vinyl, they did offer to make one for my boat. Would have been $600 and roughly 2 months to make.
