4.5 Route the vacuum source from the engine
compartment to the Powercard. Start under the
hood and locate a free vacuum port on the intake
manifold (right hand side of the engine). If there
are no free ports, splice into an existing vacuum
source and use the included Tee to connect to
the hard plastic tubing included with the kit.
Route the tube from the intake manifold to the
firewall and across to the left side of the engine
compartment. The tubing will go through the
grommet with the wiring harness. Use a long
phillips screwdriver to push through the grommet.
Be cautious not to damage anything inside the
car. Remove the screwdriver and push a piece of
wire through the hole made by the screwdriver.
Wrap the wire around the tubing and secure with
electrical tape. Pull the tubing into the car using
the wire. Once inside the car, find a good way to
route the tubing across the car to the Powercard
location. Cut it to length if necessary and con-
nect it to the silicone hose on the Powercard.

4.6 The Powercard will mount in the glovebox or
on the dashboard. If it will be in the glovebox,
make sure that its wires don’t get stretched or
pinched in any of the glovebox hinges. The split
loom plastic sheathing from Step 4.1 will help
keep the wires located properly. For a dashboard
mount, you can put Velcro on the back of the
Powercard.
4.7 Reinstall the plate, the carpet, the kick panel
trim and the two screws from door sill trim.
5.0 SUPERCHARGER PREPARATION
5.1 Working on a table, set the supercharger unit
in a position easy to work with. Be very careful
not to bump the supercharger pulley in any way
as it can easily damage the front bearing. Check
outlet manifold for debris and clean it out if nec-
essary. Install the outlet manifold as shown in fig-
ure 5.1. Get your Mazda throttle body with the
ICS blanking plate as installed in step #2.7 and
mount it to the supercharger using a thin film of
the sealant provided and the four bolts (8mm x
40) supplied in the kit.
5.2 Locate your throttle cable bracket that is bolt-
ed to your standard intake manifold and remove
the throttle cable by loosening the pinch nuts sur-
rounding the cable end on either side of the
bracket. Once the nuts are loose, you can pull
the cable out of the bracket - the grommet will
deform and let you do this. Remove the throttle
cable bracket by removing the two 10mm head-
