Im stuck not knowing what to replace and am needing to have everything working by this Thursday.. Please help

Make sure everything is grounded good. Also, check to make sure no wires are shorted. I went to pull a boat last weekend and whenever I would turn on the turn signals, my four ways would flash, then slowly fade out. Turns out a wire was shorted, taped it up and all worked fine. Just my

My truck had a short in the stock Ford 7 pin plug. It would do about the same thing as yours. I bought a new plug for $8 and switched the wires in about 8 minutes. Viola!! Just a thought if your plug looks old and abused as mine did.
