After the water treatment, use an jacketed and stranded wire and pass it through each tube of the element. Pay attention to anything that comes out on the wire. You may have to go at it from both sides because of the bends. F",

The cable does not look like Micro Motion OEM 4-wire cable. Not saying it shouldn’t still work, but I’d check to make you’re getting 12v on the black/red.
