What this part is
The 4579X is a genuine Traxxas replacement wiring harness for the 4570 EZ-Start and 5270R EZ-Start 2 starter systems. Traxxas lists the same part number in its own catalog. If the harness on your nitro model has worn out or broken, this part restores the push-button start.
The harness connects the handheld EZ-Start control unit to the engine-mounted starter components. Pressing the button on the control unit heats the glow plug and spins the on-board starter drive to turn the engine over.
Fitment
This harness works with both the 4570 EZ-Start and the 5270R EZ-Start 2 systems. Traxxas builds the EZ-Start 2 system for the TRX 2.5, 2.5R and 3.3 nitro engines. The company lists the 4579X as a stock part for the Revo 3.3 (53097-3).
Not every nitro Traxxas takes the same harness. Check the parts list in your model's manual against 4579X before you order.

What is in the package
The listing photo shows the genuine Traxxas retail bag with one harness inside:
- Multi-conductor harness with blue, black, red and yellow wires
- Black mounting bracket assembly with a clear connector housing at one end
- White connector plug at the opposite end
The package contains the harness only. The EZ-Start system needs a charged 7.2-volt, 6-cell battery pack and a charger, and Traxxas sells those separately.
Before you order
- Match 4579X against the parts list in your model's manual. Different Traxxas nitro models use different harness part numbers.
- Wire length and wire gauge are not published for this part. Compare the photo with your old harness if you are unsure.
- The starter battery, charger, control unit and engine-mounted EZ-Start hardware are separate parts.
