"Nor will a piece of 12 V automotive cable $0.00"
Sean you are right...but....my solid puller can be used at right angles where items like the muffler are in the way of a direct pull of the electrical wire. I also use a Snap on push pull spring tool https://shop.snapon.com/product/Push-Pull-Spring-Tools/Push-Pull-Spring-Tool-(Orange)/SPRG625O
It is pricy yes, but in some places, especially tight exhausts, the push part can come in handy. With a bit of creativity you can make this out of an old screwdriver. Just be sure to harden the end so it will not break off with heavy pulls. (heat and quench it)
Cheers
