The most premium wiring harness on the market for the JZ Platform!
Designed for ultra-demanding motorsport and high end builds, this harness features full modularity, mil-spec materials, and integrated power management aswell as full control of your JZ and 8HP transmission!
-
Motorsport-Spec Materials: Constructed using M22759/32 Tefzel wire and MIL-DTL-23053/16 Spec heat shrink tubing for exceptional resistance to oil, abrasion, and thermal fatigue. Complete concentric twisted construction ensures maximum flexibility without fatigue or damage.
-
Integrated Power Relay System: Features an internal high-current automotive relay setup. The system requires only a primary 12V battery feed, a switched ignition trigger, and chassis ground, handling all high-current load distribution internally.
-
Modular Engine & Driveline Architecture: Quick-disconnect modular sub-harnesses allow independent servicing, engine swapping, or hardware alterations (e.g, 8HP integration, swapping coil packs or upgrading throttle bodies) without requiring main harness re-wiring.
-
Plug-and-Play ECU Compatibility: Factory-pinned and mapped for the MaxxECU Gen 2 Race and Gen 2 Track platform. Fully repinnable and adaptable upon request for standard aftermarket ECUs (Haltech, MoTeC, Link, FuelTech).
-
Integrated Chassis Isolation: Includes a heavy-duty sealing firewall grommet for watertight cabin-to-engine-bay isolation and clean passthrough.
