Part 2 - Attaching the silver bezel onto the boost gauge (optional)
If you purchased the gauge with the silver bezel you do have the option of running the setup with or without the bezel.
If you wish to attach the bezel then you will need a bit of white glue to do so.
Drop a thin bead of white glue onto the inside part of the bezel
Place the bezel onto a flat surface and then carefully take your gauge and place it onto the bezel.
You can always install the boost gauge without the bezel and if you change your mind then you can place the bezel onto the gauge bezel and use some tape to hold it in place until the glue dries.
Part 3 - Installing the gauge
First we must remove the OEM steering column cover. Locate the 2 screw opening underneath your steering column. Carefully insert the Torx T8 screwdriver up the shaft and slowly unscrew the screw.
When you feel the screw disengage carefully lower the screwdriver, remove the screw and put it in a safe location. Repeat for the other side
DO NOT lose these screws as you will need them to secure the new column pod to the OEM lower piece!
With both screws removed you can now take the OEM cover off. Carefully grasp the cover with both hands, gently lift the cover upwards and then pull towards the steering wheel
The cloth cover on the back is held in place with a bunch of plastic clips. To remove the cloth cover on the back slide your fingernail between the cloth and the plastic and pull the cloth cover away to pop the clip off.
We will be powering the gauge from the dimmer lead in order to have the gauge change its backlight brightness with the instrument cluster.
To access the wiring you grasp the headlight switch
Push the center part of the headlight switch inwards
Twist the switch clockwise between the '0' and 'Auto' marks and it should catch and stay depressed
Now you can gently pull the entire headlight switch out
Take the gauge wiring harness and feed the black and white wired end from the front of the steering wheel towards the headlight switch.
The blue+gray wire is the dimmer wire. Using one of the wiretaps crimp one side onto the blue+gray wire and the other side to the white wire on the gauge wiring harness.
** Pay close attention to how the wiretap connector works or you will have lighting issues with the gauge.
If you look underneath the knee bolster to the far left there should be a cluster of solid black and solid brown wires which should be secured to a metal post via a screwdown nut. This is a common grounding point for the electrical system. Using the second wiretap crimp one side onto one of the black/brown wires and the black wire from the gauge wiring harness.
When this is completed you can test the gauge backlighting by plugging the gauge wiring harness into the back of the gauge and turning your headlight switch on. The gauge should light up and dim/brighten with your dimmer controls.
If you find that the gauge is too bright then you use the supplied resistor to adjust the brightness level.
To do this you cut the white wire from the gauge wiring harness in half, trim the white jacket to expose the wire and attach one of the supplied barrel crimps to one end. Repeat for the other end of the other white wire. When this is done you can then crimp the resistor inline to complete the circuit. With the resistor in place it will reduce the gauge backlight level to closely match the instrument cluster.
If you are happy with the way the gauge lights up then disconnect the wiring harness and vacuum line if attached from the back of the gauge. Push the headlight switch back into its opening until you hear it click into place.
You can now thread the wiring harness and vacuum line through the steering column gauge pod opening and seat the pod onto the steering column. Attach the wiring harness and vacuum line to the gauge and push the gauge into the opening and adjust its position to your liking.
Part 4 - Securing the gauge
The gauge is held in place with only friction and it will slightly move. In order to prevent it from moving we need to secure it with a bit of white glue.
With the steering column pod in place insert the boost gauge into the opening and align the gauge to the position you like.
Use some masking tape to secure the gauge to the pod in order to lock down its position
Spread a bead of white glue between the edge of the pod and boost gauge
If you set the pod upside down to let the glue set it will run around the entire edge of the gauge to completely hold it in place.
Let the glue dry before proceeding with the next step. Using a hair dryer does help speed up the process.
Part 5 - Finishing the installation
When the glue has dried you can now complete the installation.
Carefully connect the wiring harness to the back of the gauge
Connect the vaccum hose to the boost gauge
Make sure the wiring harness and vacuum line are clear and attach the column pod back onto the lower steering column and use the 2 Torx 8 screws to secure it to the lower piece.
You can now reverse the process to reattach the knee bolster and fuse cover.
Congratulations! You are finished!
