47-55.1 Rewiring the 54

[hogfarm]

I have my 54 in the shop for the winter. I am determined to get it finished this winter. To many things got in the way last year so the truck never saw the road.I am rewiring under the hood just to clean it up. I am not going to replace all the wires so I will need to splice a few. In the past I always soldered all the wires and used heat shrink . But I saw some connections the come with solder and water proof covers, and just use a heat gun. Has anyone used these? If so what do you think
