Description

Holley EFI benchtop harnesses are designed for benchtop testing and setup of HP, Dominator, Terminator X, Terminator X Max, and Sniper ECU's, as well as 7 in. dashes. They are great for ECU diagnostics that do not require a running engine, firmware updates, or 7 in. dash calibrations. The harness has pre-terminated connectors for the following sensor inputs: CAN, Crank, Cam, TPS, Input (1), P1A, Main Power, and Sniper EFI connectors for a Sniper main harness. Also includes a power switch for quick setup in your workspace. Power and ground flying leads need to be connected to your battery or power supply (not included).


Key features:

* Terminated connectors for multiple EFI inputs
* Included power switch allows for a quick "install" on your test bench
* Optimal for ECU diagnostic, firmware updating, and pre-configuring dash layouts
* Works with HP, Dominator, Terminator X, Terminator X Max, and Sniper ECU's, as well as 7 in. dashes
* Has pre-terminated connectors for these sensor inputs: CAN, Crank, Cam, TPS, Input (1), P1A, Main Power, and Sniper EFI main harness connectors
