Okay since no jethro, anyone. He helped me with the installation stuff to get my 250 sho to read temp on my lowrance . Now i have replaced it with a new 250 sho and i no longer have a temp reading. The mechanic insist he hooked up all wires. I looked and it appears that the cable is hooked to a white pigtail on passenger side of block.

Any ideas. Did cable go bad, is it hooked to the wrong place for a 2020. It's a 2 hour drive back to shop, so hoping to fix myself.

If I have to replace the cable, what do I order.

The engine temp gauge in dash works fine., but it doesn't read in degrees. And used completely different cable and probe.
