Easy wire/cable placing

Hello everyone,

I've got very basic Solidworks and I'm not sure if it has this future (or where to look, coz I can't find it).

I have an assembly: electrical boards, metal cases and now I have to place alot of cables around. I know I can use 3D sketch but is there any other way included in basic Solidworks package or an easier way or addon? plugin? Just curious. Preferably free addons, coz I don't think my boss will go on buying more for my part.

Thanks alot in advance for your advises.
