according the old post from techguy512

pin 9 is input from sensor
pin 8 is sensor return (gnd)
pin 7 is sensor cable shield

pin 8-9 80 ohms (+/- 20 ohms)
pin 7-9 infinity (open)
pin 7-8 infinity (open)


red is positive port 9
yellow is shield port 7
black is negative port 8

in the even oldr post by OldPokey diagram states

pin 9 is input from sensor
pin 7 is sensor return (gnd)
pin 8 is sensor cable shield

but I suppose as those two (7,8) are grounded together it does't metter ...??
