17.04.2004: The kit |
A Cyberdyne Ultragage boost/vacuum gauge kit (part #A213E061Y) bought on
eBay. It contains a gauge, a sender, some tubing and other supplies.
|
|
05.11.2005: Vacuum line |
Locate the vacuum line going from the throttle body to the bypass valve.
|
|
05.11.2005: Tap |
Tap into the line (or replace the hose to keep a spare handy) and insert
a tee.
|
|
05.11.2005: Sender |
Connect the sender unit and attach it into a secure spot. Tie the cable
so it doesn't dangle around.
|
|
05.11.2005: Fuse box |
Undo the 10 mm nut holding the fuse box. Lift the box and move it aside.
|
|
05.11.2005: Firewall |
Locate the wire cluster going throught the firewall next to the clutch
cable (or the clutch line). Unwrap the tape and cut the zip tie around it.
|
|
05.11.2005: Lower panel |
Undo Torx T25 screws on the lower panel. Unscrew the OBD II connector.
|
|
05.11.2005: Fuse box |
More screws around the fuses. Finally, a 10 mm bolt at the bottom,
and the trim panel comes off.
|
|
05.11.2005: Fuse box |
Removing the fuze box is not absolutely necessary, but it gives you more
room to do the wiring. Three Torx T25 screws.
|
|
05.11.2005: Wire cluster |
The rubber gaiter securing the wire cluster is found next to the clutch
pedal.
|
|
05.11.2005: Pipe |
Push a piece of PVC pipe between the wires and the rubber sleeve so
it comes out on the engine side.
|
|
05.11.2005: Wire |
Slide the sender unit signal wire through and remove the pipe. Zip-tie
and wrap the rubber sleeve on the engine side.
|
|
05.11.2005: More wires |
Connect a piece of wire to the ground nut under the dash. Connect another
wire to the cigarette lighter fuse for a source of switched power. It is
a good idea to have the battery disconnected prior to this.
|
|
05.11.2005: Dash |
Many 2"1/16 gauges will fit right in, but you will need to cut the plastic
inside the headlight switch socket. I decided to pop the dashboard to
attach the display from the rear. Follow
this
guide for dashboard removal.
|
|
05.11.2005: Wiring |
Trim and crimp the wires from the sender, as well as your power and ground
lines.
|
|
05.11.2005: Gauge |
Attach mating connectors to the gauge display unit.
|
|
05.11.2005: Test run |
Connect the wires, double check everything and do a test run. After
you start the car, you should see 15-16 Hg of vacuum at idle.
|
|
05.11.2005: Headlight switch |
The headlight switch will rest inside the dashboard set to the
"headlights on" position. Saab DRLs run the headlights full on anyway, so
it won't make much difference.
|
|
05.11.2005: Wrapped |
Wrap the switch into something so it doesn't rattle inside the dash.
|
|
05.11.2005: Finished |
Job complete. The gauge is nicely illuminated at night.
|
|
07.03.2006: On |
It's clearly visible in the bright sun.
|
|
07.03.2006: Off |
Nice and stealthy when the car is shut off.
