This Bus Interface Module is designed to read engine information from the Holley Sniper 2 kits. The module is connected 
to the Holley EFI through the CAN-bus plug on the EFI harness. To connect your Sniper 2 to this product, disconnect the 
4-pin threaded connector that links your throttle body to the Sniper 2 handheld. Then, connect these cables to the 391205 
included in this kit. Connect the 391205 to the BIM-01-2-HLLY using the included 394298 harness. 
 
There are two interface (I/O) ports on the BIM-01-2-HLLYmodule.  Either one can be connected to the instrument system 
or to another module, allowing several units to be daisy chained together.   

Cannot daisy chain with GPS-50-2

Do not connect the I/O port to anything other than a Dakota Digital control box or BIM.  
Do not mount the module in the engine compartment; as 

it should be mounted in the vehicle’s cabin. 

 
The engine and transmission information that is available from the unit depends on the EFI kit and module programming 
and add-ons. For specific data readings: see individual setups below for each version of Holley EFI system below. 

 

Note: If you are not utilizing a Holley handheld display, you must disable the HND setting within this BIMs 

setup menu (Page 9-10). With the HND setting disabled, you must unplug this BIM unit if you perform a 

Holley firmware update using Holley’s CAN to USB adapter. 

 

A GPS-50-2 CANNOT be linked (daisy chained) to a BIM-01-2 with a BIM cable. 

The two units cannot talk to the display control box at the same time.
