The original braided cable just ran next to the wires and was enclosed with foil. Since I have made the splices, but not enclosed in foil yet...do you think I will be ok with splicing the home made stripped wire next to the wires, all bundles with foil? Or is it recommended to do the "bunch" method and wrap with foil? Is the HVAC foil tape better than household aluminum foil? The original is very thin 'crepe' style....almost like a wrapping paper or a pinata streamers...to paint a picture.
