This is what's
required to add a factory trip computer
to a 1993-1995 Audi 90/90
quattro.
Note: The wires, connectors and trip computer/autocheck modules I
have been working with have been from several '88 90 quattros.
Yours should look similar, but might have different numbers of
wires/configuration/etc, but the basic installation is the same.
Audi Parts required:
•
trip computer/autocheck modulefrom a 1988-1992 80/80
quattro or 90/90 quattro or a 1990-1991 coupe quattro•
switch
for the trip computerEarly B3s will use a switch in the
center console (by the heated seat/defrost switches), this is the
easiest switch to install. The other is the later B3/coupe
quattro/B4 style at the end of the wiper stalk. If you have a mid
to late '95 with the newer style airbag wheel you'll probably need an
'96 to early '98 A4/A8 stalk assembly. [/size]
•
wiring
pigtails from the donor carpigtail = connector plus as much
wire as you can get cut out of the car.
The trip computer is a
10-pin black connector, the connector for the console-style switch is
blue (I haven't tried the wiper stalk, so I do not know how what color
that connector is), if you plan to install the autocheck system too, the
autocheck is a 26-pin white connector. Both the trip computer and
autocheck plugs are connected to the autocheck/trip computer assembly.•

parts required:
•
electrical tape•
splice
connectors, spade or quick disconnect connectors and wire taps.•
some 16-22 ga. wire•
full tank of gasfor
calibration of the trip computer
Making
the wiring harness
1.) First remove the old taping material from
both the trip computer and switch connectors.
2.) Next, install
splice connectors to all 5 wires on the switch connector (blue). They
will match up exactly with the wiring harness for the trip computer
(black). (blue, black, brown, grey, green)
updated '07 note: If you're using a
stalk switch wiring colors are the same except the illumination wire is
not utilized if present in your pigtail.
3.) Now tape the 5
wires together as tight as you can (will help when you snake them behind
the dash). You will only need one other wire out of the trip computer
connector (black) which is the yellow wire. This wire is referred to as
the consumption wire. I spliced in a piece of black wire to the yellow
wire in the trip computer pigtail (see below)
note: The rest of
the wires are not used/needed on a 93-95 Audi 90/90 quattro (they're
taped off in the top/right of the left picture below).
