I am working on my dash. MK4 complete kit delivered Nov 2019. Gauges are installed in dash. But having issues with the wiring. Every post and picture I see shows the Vintage gauges with 3 sets of wires. One (red/white/black) daisy chain for needle, power and ground, one (black) daisy chain for the backlight/dimmer ground, and one for the sender connections.
All of my gauges only have the red/white/black daisy chain and senders. No black wires. Even my instructions only show one. What am I missing? Will the needles and dials be illuminated? Will the light switch dimmer adjust both the needle and face? See attached pictures.
Sorry for the simple question, but can't figure it out. Thanks as always
