Engine Loom Essential Connector Set – Toyota 1UZ-FE (non-VVTi)
This connector set includes the essential engine connectors required to make a new wiring harness for a Toyota / Lexus 1UZ-FE engine (non-VVTi only) when using an aftermarket wire-in ECU such as a Link G4X StormX or similar with the factory air flow meter removed.
This connector set includes:
- 8 x Fuel injector connectors (3 variations available – see notes below)
- 1 x Alternator connector (2 variations available – see notes below)
- 1 x Idle control stepper motor connector (optional)
- 2 x Ignition coil connectors
- 1 x Crank angle sensor connector
- 1 x Cam angle sensor connector
- 1 x Throttle position sensor connector
- 1 x Water temperature sensor (ECT sensor) connector
- 2 x Knock sensor connectors
- 1 x Oil pressure sender (gauge) connector
- 1 x Water temperature (gauge) connector (suits engines from 10.1992-on)
All connectors come with connector housing, terminals and seals.
As this set consists of the just the essential engine wiring connectors required for using with an aftermarket ECU, other engine wiring loom connectors such as the factory oxygen sensor connector and AFM/MAF connector are not included. Note also that the ignition module (igniter) connectors are not included as the factory igniters are seldom retained on 1UZ-FE engine transplants.
The 6-pin idle control stepper motor connector is offered as optional with this connector set as some aftermarket ECU’s do not support idle control stepper motors, meaning the factory stepper motor becomes redundant in many cases. If your ECU doesn’t support an idle control stepper motor, you may also be interested in our Toyota 1UZ-FE Idle Speed Control Solenoid Conversion Kit
