FAST™ XIM™
Thank you for choosing FAST™ products; we are proud to be your manufacturer of choice. Please
read this instruction sheet carefully before beginning installation, and also take a moment to review the
included limited warranty information.
XIM™ Unit Installation
The XIM™ unit itself is designed to withstand under hood temperatures but needs to be mounted in a
location that allows for some airflow in and around the heat sink. Also keep in mind that the XIM™ is
not 100% waterproof and should not be mounted where it will be exposed to direct spray. It is also
good practice to mount the XIM™ with the connectors facing down. Typical installation locations
would be on the firewall or inside the vehicle cockpit.
Wiring
These wiring installation instructions are specific to the wiring harnesses manufactured by FAST™
only. If you are using a wiring harness other than the ones offered by FAST™, please contact your
dealer for instructions for that harness.
FAST™ wiring harnesses are labeled on each of the connectors to simplify installation. Your
application may not require the use of all the connectors in the harness. And not all harnesses will
include every connection listed below. You may also require additional accessories such as relays,
sensors and other specialized connectors to complete your installation. All of these are available for
purchase from FAST™.
Crank
:
This connector simply plugs into your crank pickup. Depending upon your application, it may be
found near the harmonic balancer or towards the back of the engine near the flywheel. The crank
sensor is used by the XIM™ to determine crank speed and position.
Cam
:
This connector plugs into the cam pickup. Depending upon your application, it may be found on the
end of one of the cylinder heads or the front of the intake manifold area. The cam sensor is used by the
XIM™ to find the start of the firing order.
CAM HALL EFFECT
:
This connector plugs into the CAM HALL EFFECT connector on your FAST™ XFI™ Main Harness.
This connection feeds cam and crank signals from the XIM™ to the XFI™. The XIM™ crank and cam
outputs are always wired to the XFI™ discrete crank and discrete cam inputs regardless of what type
of pickups (inductive or discrete) are connected to the XIM™.
