STANDALONE LS1 LOOMS- Perfect for your LS swap!
HOW IT WORKS:
- Send me your LS1 loom via mail, once received I will asses condition of the harness & discuss options for your swap, then I’ll modify your loom to make it standalone
- Ensure its all working on my live test rig
- Sent back to you with a set of instructions and all hardware required.
Standalone means the engine and transmission will work independently of the body of the vehicle, several outputs as listed below are available and can be connected to the body of the vehicle for complete integration.

Stage Three Loom Includes:
  • Modified factory loom to be standalone
  • Super Simple Installation 3 wires to get running  PLUS Two Speed fan control, MIL (Engine light) output and Shift Light Output!
  • Sealed BUSSMANN Relay and Fuse Box for coils, injectors, ecu, sensors, 2x Thermo fans Hi & Lo (MAXIMUM 240w per fan) 1x Fuel pump (MAXIMUM 240w Pump) 
  • 100 amp main fuse and measured length of cable to mount to fuse box
  • Measured lengths of twin core wiring to connect fuel pump, fans and ignition signal
  • OBD2 Port to enable tuning and diagnostics
  • Labelled computer controlled outputs such as Tachometer with shift light, Speedometer, Neutral Safety Switch, A/C Input, Reverse Lights & Engine Light
  • Comprehensive plain English 12 Page install instructions to help you install and better understand the electrics of an LS1.

If you have a factory engine computer, it will not function without having the VATS (vehicle anti theft software) removed - this is an additional service and is available - HERE 

If you are unsure which stage of harness best suits your build, please check the comparison chart in the product images.

*NOTE*  This kit is ideally used when converting to EFI from pre EFI vehicle and using mild fuel pumps and fans which require lower power draw. 20a continuous and 25a peak draw is maximum allowable per circuit.
