ATR engine harnesses are professionally hand made. No wire color changes or jumps, just a specific color all the way through to where it needs to be. This will greatly reduce the chances of errors that may occur during modifying the OEM harness or a GY6 donor harness. ATR wire harness is 95% plug and play, minor simply adjustment is needed to get the harness to work. Please read the notes below.

With the use of this harness, the stock ECU and electric fuel pump will no longer be needed. A vacuum fuel pump is required.

The Honda Ruckus factory controls will plug directly into this harness, all functions of the controls will be usable like OEM!

There are 2 extra wires running from the middle (stock fuel pump location) to the front end(inside battery box), just in case the end user would like to wire up their electric OEM fuel pump or other accessories, such as a temperature sensor, tachometer, etc. they are there specifically for future modifications and additions- so there's no need to tear up the wire harness to add wires.

ATR plug and play harness also have a extra yellow stator wire already pre-wired incase there is a bad stator and you end up buying a new stator that requires the extra wire/s (example: 8 pole stator went out and you wanted to upgrade to a 11 pole since you're purchasing a new stator, you can use the extra wire).

8 pole harnesses: Starter solenoid LED Ready Flasher Relay Engine Kill Relay Rectifier for 8 pole Spark plug coil and wire

11 pole harnesses: Starter solenoid LED Ready Flasher Relay Engine Kill Relay Rectifier for 11 pole Spark plug coil and wire

Notes from ATR:

For 2003 model and below the gas indicator plug plugs right into the harness, however for 2004 and up the connector needs to be cut out and butt together directly to the harness (you could use the connector from your stock harness). The Key ignition plug will also need to be cut out butt together directly to the harness (you could use the connector from your stock harness as well).

Included voltage regulator/rectifier may/may not be compatible with your stator. We recommend using the included rectifier with your engine package to ensure that both are compatible. The included rectifier on the ATR harness is a project starter, it allows you to get your project going in case you're missing this component. Product Tags
