i need a little wiring help w/ multi function temp sensor [88 90q]

[no1of consequence]

happy friday all,

i'm wondering if anyone with the bentley wiring diagram [for an 88 90q] can
confirm a few wire colors for me? i'm reterminating my multi function temp
sensor with a correct plug and i need to know which wires go to which
terminals on the sensor. My mechanic installed a new sensor but  cut the
plug + used cheap crimp connectors, 1 of which broke already. The car since
sprouted sensor-related symptoms [gauge inop, 'swimming thermometer' on
autocheck upon starting]. i'm trying to rule out bad gauge, bad sensor, etc
but would 1st like to rule out the wiring. and, of course, the wire colors
on the new plug i got dont match my car at all. [thanks audi!] ;)

colors ive got coming from the car to the sensor:
blue w/yellow stripe [pretty sure that's ground - unused in new sensor]
Blue w/white
blue w/red
black w/blue

anyone? thanks a ton - i REALLY appreciate it.

jim
