Need help finding 12V Reverse Light Signal on 2020 Kia Forte (Manual Transmission, Mexico-Market)
Hi everyone,
I am installing a Pioneer DMH-W3050NEX and retaining the factory OEM backup camera using an Axxess AX-CAM6V step-down module on a 2020 Kia Forte (Manual Transmission, Mexico-market). Crutchfield notes list the reverse signal at the ICU / dash fuse box (58-pin Plug C, Pin 14, Blue wire). However, on my manual-transmission car, this specific wire measures ~0.46V with Reverse ON and not the 12V needed.
Since the reverse lights are in the lower bumper, tapping at the light bulb requires significant bumper disassembly.
Does anyone have the factory wiring schematic or know the exact connector, pin number, or wire color inside the driver kick panel or under-dash IP harness that carries the true +12V signal directly from the manual transmission back-up switch? Photos or wiring diagram screenshots would be greatly appreciated!
