Temperature sender/sensor & harness

[Soundmound]

Hi all.

I had a non function temp gauge from day one. I assumed the cluster had issues as most of the other gauges had issues also. However, going through the coolant system to start gathering parts for a one shot refresh of it, I found the temperature sender/sensor was in rough shape, had been e-taped and had some old rubber hose section around it for "insulation". So, this begs the question anyone know where to get a harness? Also, without pulling it how do I know which sender I actually have?
