$8 or $7 - 56" e-brake cable extension cord 2 items are available. Items have seen light use. Uses 4-pin JST-SM connector, only pins 2 and 4, as used by Grin Technologies (ebikes.ca). Note that one of these items (the one in the photo) has a chipped male JST-SM connector shroud. The item is functional. But, the price is $7 for that item.
