INSTALLATION
1. Disconnect the positive (+) battery cable from the
positive battery terminal.
2. Locate the VIC injector harness in your kit. Remove
existing injector harness and install the new VIC injector
harness (see figure 1, and figure 1A.)
3. Locate the VIC power cable assembly in your kit
(see figure 2.)
3a. Connect red wire of power cable assembly to
positive terminal of car battery.
3b. Connect black wire directly to negative car batter
terminal. NOTE: If chassis ground or engine block
ground is used. Be sure that ground between engine
block/chassis and battery is good.
3c. Connect pink wire of VIC power cable assembly to
12V switched power. NOTE: Be sure the 12V switched
power source has power during engine cranking.
4. Connect 3-pin male Packard connector from the VIC
power cable assembly to 3-pin female Packard connector
on VIC. (See figure 3)
5. Connect 10-pin male Packard connector from VIC to
10-pin female Packard connector on injector harness.
(See figure 3)
6. If using an ACCEL/DFI Spark/Fuel Management ECU
skip this step. Splice any one injector signal wire from
your ECU to the round 5 pin Packard connector

INTRODUCTION
Thank you for purchasing the ACCEL/DFI Variable Injector
Controller. The Variable Injector Controller (VIC) unit was
designed to give the user the ability to adjust individual
cylinder fuel delivery on the fly. Without complex
computerized tuning tools, the user can extend fuel
delivery time to each cylinder by up to 25%. The VIC also
gives the user the ability to use high flow, low impedance
injectors in systems designed for high impedance injection
only, such as the ACCEL non-sequential ECU. (NOTE: low
impedance injectors are usually around 4.7 Ohms in
resistance or less. High impedance injectors range from 12
to 16 Ohms in resistance.)
This manual is written to assist you with the installation of
your Variable Fuel Controller. Please review it carefully,
before beginning your installation. If you have additional
questions, call us at our ACCEL/DFI technical service
number (216) 398-8300 EXT 5, between the hours of 8:30
A.M. and 5:00 P.M., Monday through Friday (Eastern
Standard Time).
