Unless it's nylon, just toss the provided 'cable'. 'Natural fibres' such as cotton will have tons of tiny bits of thread coming off everywhere... In that case, find yourself some fine wire, get a few (5-6) strands together and twist them (attaching both extremities if the strands around a, say, cocktail stick, really helps here!
Use the kit's hooks. Attach with superglue at a few spots before priming/painting them come back on ot with a fairly dark thick wash (black with 50% thinner). Then use the lead of a pencil to rub graphite over the cable to give it its metallic look. The pencil is also useful to make tiny 'metal' marks/sratches near bolt heads, engine access panels and anything standing out (handles, edges, and also the teeth of the drive sprockets!)
