BLOCK GND:
This wire is to be connected to a good paint and rust free ground source on the engine block of your
vehicle. It is only used for the LS1/LS2/LS6/LS7 engines and will not be found in other harnesses.
DRIVER COILS:
This connector plugs into the GM factory coil harness plug on the driver side valve cover. It is only
found in the LS1/LS2/LS6/LS7 engine harness.
PASSENGER COILS:
This connector plugs into the GM factory coil harness plug on the passenger side valve cover. It is only
found in the LS1/LS2/LS6/LS7 engine harness.
COILS:
This connector plugs into the FAST™ coil harness that comes with your XIM™ unit for the Mopar
Hemi applications. One coil harness is used with a 5.7L engine and another is used with a 6.1L engine.
All coil connectors are clearly labeled with cylinder numbers.
CRANK JUMPER:
This jumper connects to the CRANK connector on your FAST™ XFI™ Main Harness. It loops
together the unused wires of the ECU’s inductive crank input.
DIP Switch Settings
Your XIM™ unit is configurable for different engine applications. This is accomplished by using 8
DIP switches found inside the back cover of your unit. To access the DIP switches, simply take the lid
off by removing the 5 screws, being careful not to tear the gasket beneath the lid. Below you’ll find a
handy list of the current engine applications covered with your XIM™ unit and the switch settings that
are required for each. The “on” position is marked on the switches.
