The video describes what often happens when liquid gets into the system. As to it being the connector and the cable as in his case is a possibility. I would open the system up and inspect the trackpad connections. more often I find the solder joints corroded or caked with junk. I rarely use ‘Spray Contact Cleaners’ of any kind. Most have oil in them which you really don’t want to spray all over the place! Some also have chemicals which can over time damage things as well.

I use distilled water (100% H2O and nothing else in solution) as well as reagent quality 85% or better isopropyl alcohol. I would take the trackpad out lean the trackpad on a paper towel so the solution doesn’t ender into the layers of the trackpad and used a soft toothbrush clean the areas effected with the distilled water - [https://www.usgs.gov/special-topic/water-science-school/science/water-qa-why-water-universal-solvent?qt-science_center_objects=0#qt-science_center_objects|The Universal Solvent!] I then rinse the areas with isopropyl alcohol as it will help in getting the last bit of water out.

If that fails I would replace the trackpad and the cable.
