Chase Bays Engine Harness - Toyota 1JZ-GTE | 2JZ-GE | 2JZ-GTE

***Now sold with brand new connectors, making this a 100% brand new engine harness***

This harness is for 1JZ-GTE & 2JZ-GTE engines using a STAND ALONE ECU (AEM, Haltech, Motec, etc) This eliminates the OEM o2 sensor, all VSV's, Power Steering Asist, and requires MAP & IAT. For 1JZ-GTE & 2JZ-GTE with OEM ECU, click here

There are so many features these have to offer, this kind of innovation and flexibility has never been done in our industry.

The Toyota/Lexus 1JZ-GTE and 2JZ-GTE Motors. There’s about 7 variations of these motors. All remotely the same harness build. Variants include, coil packs or spark plug wires, crank/cam sensor & pickups, different ECU’s, injectors, ETCS System, MAF or MAP, and a few others. We’ve done the research and become very familiar with these variants. So even if you’re not familiar with the electrical components, we are. The harness can plug into, basically anything. We use the same black 16pin connector near the ECU plugs on all of our harnesses. It has all the chassis inputs and outputs you need. The opposite side of this connector is what we can adapt to YOUR chassis. When ordering this product it will ask you all the info we need to know via drop down menu’s. This is all the innovation and flexibility mentioned above. No one else knocks out 20 birds with 1 stone.

• 
  Completely redesigned and reinvented Toyota engine harness that fits perfectly and sports a stealthy look 


• 
  Turn around time is 2 WEEKS OR LESS. If you need something expedited we can probably do it, just call or email

In the initial mockup and R&D process the harness was completely re-designed and re-measured to fit perfectly along the motor. No wasted length on any of the sensor looms. The harness now routes underneath the intake manifold and each connector to its dedicated location. This makes for a great look, an easier install, an engine bay with less clutter, and much easier to work on when under the hood. Amphenol Mil Spec connectors are used at the Coil Packs and Boost Solenoid to keep options open for different setups. This means, if you’re running OEM Coil Packs and you get a Stand Alone and want to run our LS2 Coil Pack kit or any other coils, all you have to do is call us and we make a new sub-harness. Then you’d just un-plug the existing Coil Pack sub-harness, and plug the new sub-harness. It’s that easy.

TECH SPECS

CM1 harness – The CM1 harness features all new commercial grade, high heat, thin jacketing wire (rated from -49° to +257° F), individually striped for easy identification and all new sensor plug pins. It is covered in full flame retardant nylon sleeving (Operating Temperature Range -103° to 257°F; Melt temp 446°F), and adhesive lined heat shrink. All engine harnesses go directly to the ECU clips, and include all the needed wiring and plugs to make the harness plug and play to your vehicle. The harness is built with aesthetics and functionality in mind. Our harnesses have had a lot of R&D done for proper wiring technique, with all shielded wire used where needed. It features a stealthy look but is also easily accessed, keeping the motor easily worked on. This harness is great for someone looking to clean up their engine bay and replace the used and worn down stock harness.



CM2 harness – The CM2 harness features all the same great aspects and design of the CM1 harness but adds a Mil Spec quick disconnect firewall connector and Raychem connector boot. All CM2 harnesses are designed to mount to the OEM harness entry hole or former AC oval hole (if AC is eliminated) It also includes a complete new custom charge harness (for Alternator and Starter power wires). This harness is perfect for someone who wants the option of very easily removing/disconnecting the engine harness. Not to mention a very shiny firewall connector

CM Mil Spec harness –  The Mil Spec harness features; All new sensor plug pins, all new thin jacketing wire (rated from -49° to +257° F), Raychem DR-25 heat shrink (operating temp. -103° to +347° F), adhesive lined heat shrink junctions, Raychem break-outs/junctions where needed, Yellow sensor labeling, and Mil Spec quick disconnect connector w/ Raychem shrink boot. The harnesses go directly to the ECU clips, and include all the needed wiring and plugs to make the harness plug and play to your vehicle. The harness is built with aesthetics and functionality in mind.Our harnesses have had a lot of R&D done for proper wiring technique, with all shielded wire used where needed. It also includes a complete new custom charge harness (for Alternator and Starter power wires). The best harness money can buy. Built with high performance and full functionality in mind, the same materials and assembly has been used on the world’s fastest race cars across the world for years.
