The old one has a broken lead up within the waterproof harness. For the sake of convenience I simply cut and stripped the leafs from the lights and slipped into the provided adapter and then plugged in thenew transformer to an extension cord. Important to note that this replacement unit is NOT rated for waterproof or outside conditions. I am using it in a sheltered area and will take additional steps as well as actually taping the bare wire leads. This is actually just a test installation to verify that it would operate correctly for my application. I've included a picture of the original transformer output specifications, this seems a little bit brighter. Overall functional, value for money and delivered overnight. Review: Works - Works great for running a couple 12v things in my 3D printer enclosure. My only compliant is that the screws to attach wires are very small and recessed. I have to find my tiniest screwdriver for them. It would be nice if they were more accessible. ## Features - Output: DC 12V 4A / 4000mA 48W, 3.6 Ft Cable, DC interface size: 5.5mm x 2.5mm (and compatible with 5.5mm x 2.1mm) - It perfect replacement for 2A / 2.5A / 3A / 3.5A as amperage isnt forced.
