is an exact science that ACCEL has made simple. This manual
is written to assist you with the installation of your new

Prior to starting your installation, please verify the contents
of your ACCEL/DFI package. You should find the following

Injector Wire Harness (IWH)
Manifold Absolute Pressure (MAP) sensor

If you are missing any item,
please contact your dealer immediately.
Although the package you just received is designed to allow
you to convert a carbureted engine to fuel injection or allow
you better control over your present fuel injected engine, it
does not include the hydraulic portion of the installation.
If you need a fuel pump, filter, fittings, etc. Contact
your ACCEL EMIC center for the proper ACCEL/DFI part
numbers for your application.
