Review: After removing boat from lake, I plugged my trailer back into the truck. Few minutes later lights went out. Fuses were good, wireing seemed to be ok but no lights. Bought this adapter because it has 4 & 5 connection points. Plugged it in and all the lights work. Old adapter apparently shorted inside. This is a great choice to plug in 4 & 5 different types of trailer lights.
Review: I like that it can support two harnesses. Excellent idea
