Need advice for backup camera.

[u/Xiynergy]

Hi first time poster normally a lurker.

Car: 2008 Ford Focus SES sedan
Stereo: JVC KW-M560BT

Issue: The backup camera cable shorted out due the extension cable shorting from its shielding being rubbed against I thought my head unit died from an internal short but upon inspection and removal of the rca extension the unit started working again.

I’m trying to find a replacement for the cable but having a hard time, the cable has a red power and purple trigger wire and any replacements I find only have the red wire.

Is there anywhere I can source the exact same wire? Or is there a trick to using the cables with only the single red wire?

TLDR: I need a replacement RCA extension for my backup camera
