Description

The LS Harness Fuse and Relay Box is a plug-and-play power distribution solution engineered to work in conjunction with the Link LS Terminated Engine Harness. It reduces vehicle-side wiring to just two to four flying lead connections — Battery 12V, Ignition Switch, and optionally Fuel Pump and Cooling Fan — making it possible to have a fully operational engine management wiring system with minimal fabrication.

  • IP67-rated fully sealed Busman enclosure for reliable operation in harsh environments
  • Supplies fused power to all engine and ECU-connected devices and manages ECU hold-power logic
  • 3 ECU-controlled high-current relay outputs for drive-by-wire engines (fuel pump and dual fan circuits)
  • Flying leads are 1500 mm in length; main bundle connecting to engine harness is 500 mm
  • Manufactured using genuine Song Chuan automotive relays, high-temperature TXL wire, and ultrasonically welded splices

This box is the ideal companion to the Link LS engine harness for LS engine swap projects, eliminating complex relay and fuse panel fabrication and ensuring a clean, professional installation.

Specifications

  • Highly recommended item to greatly simplify the wiring connections between the Link LS Terminated Engine Harness and the car chassis.
  • When added to the Link LS harness the user only needs to connect 2 to 4 flying lead wires themselves to have a complete wiring system capable of running an engine - no special crimping tools, splicing or complex circuits required. The 4 connections are; Battery 12V, Ignition Switch, optionally Fuel pump and Cooling Fan.
  • Provides fused power to all engine and ecu connected devices, takes care of the often complex "ecu hold power" wiring for models with stepper motor idle valves, provides 3** high current ecu controlled outputs for direct fuel pump and fan connection.
  • Fully sealed high quality rugged Busman enclosure, IP67 rated.
  • Made in USA with genuine high quality Song Chuan automotive relays, high temp TXL wire, ultrasonic welded splices.
  • The 4 flying leads for connection to Battery, Ign switch, Fuel pump and Fan are 1500mm length, the main bundle that connects to the engine harness is 500mm length.
  • 3 ECU controlled relays are available with DBW engines, only 2 ECU controlled relays are available with stepper motor IAC engines (intended to be Fuel pump and Fan supplies).
