Help, I have an 8-year-old in-ground pool. All equipment is Pentair. The large (only) pool light (Intellibrite) went out last summer. I purchased replacement with hopes of switching it out myself with some YouTube instruction. Problem is, I cannot locate the junction box anywhere. I've checked inside diving board and throughout yard. Main panel is about 35 feet from light on wall of house. I've attempted to pull on the cord and it literally has no give to it whatsoever. I've called professionals, but they only wanted to charge me $2k for light and install. When I told them I already had light, they lost interest (probably significant markup). Any thoughts or known contractors that could do the job before October?
