anyone ever replaced the OE battery cables on their car? i looked around for replacements and nobody in town even had a set in their catalogs. they told me it was a dealer-only item, so i went ahead and ordered them from the dealer. the dealer told me there's a fusable link and a sensor or something in a couple of the wires. is this BS? do i really need to drop $110 on mopar wires or can i get some brand-x cables from pepboys and still be ok? thanks
