so are these needed or would they already be installed?
That makes 6/8 wire (signal wire) red on the brake connector. I was mainly confused if the + (POS) was 6/8, or if signal.
black = POS, speedo pin 2
green = ground, and/or speedo pin 3
red = signal, speedo pins 6/8
As you can see, I took my chances with the Amazon version of the sensor.
