2002/Auto/2.0L Back-up lights don't work
 

LHD Chrysler Neon 2002, automatic, 2.0L

Back-up lights don't work. Gearbox works fine and gears are shown in dash correctly. Bulbs are OK, ground is OK, fuse B/U LP SW is OK. I assume that gear selector switch is OK as I see right gears in dash.

I connected power supply to C105 connector which is under the kick panel and back-up lights work, so the problem is somewhere further in front, circuit from C105 to back-up lights is fine.

Thank you for any help.

Faulty neutral safety switch?
