Are you talking about the two wires on the outside of the cylinder that lead up to the heat sink? If so, those were molded into the castings on the pyro models, not added on pieces as on the hero models. For the most part, I'm happy building the pyro as a pyro, and accepting these castings for what they are. These castings are pretty rough, lots of bubbles and imperfections, and I'm fine with not trying to fix everything to being perfect. It's part of the pedigree of this model. The paint scheme is going to be that of Red 3, which got blown up, so that's appropriate.
