01-07 Hayabusa Custom Injector Harness



Why deal with the hassle of chopping your factor fuel injectors off and trying to splice new ones on for your aftermarket fuel injectors.  This injector harness replaces the factory one on your 01-07 Hayabusa and is intended for Bosch style injectors like the MPS injectors many out there like to use to get more fuel capacity out of their fuel system.

Throttle position sensor is wired in as well as bringing out 3 signals for datalogging on a separate (optional) connector:

  • Injector #1 ground signal – datalog your duty cycle for fine tuning
  • Throttle position sensor signal
  • Sensor ground

These are custom built, I can do other injector types as well.


Please note that while I do my best to ship items the business day after they are ordered, I am not always able to do this.

If you have an urgent need for anything, please email me directly greg@boostbysmith.com.

Domestic:  I ship most packages USPS priority mail, which is advertised as 2-3 business days.
Smaller items with shipping rates at just a few bucks are sent USPS first class mail.
I can ship UPS ground as well.

International:  Due to long delays with USPS during Covid 19, I am only shipping via UPS.
The customer is responsible for any brokerage/customs fees.  My site is setup to add $55
for international shipments as this is the worst case for UPS with rare exception of a remote service
zone fee which I will contact you if this is the case.

In the event that shipping is less than $55 I will send a refund.  Feel free to contact me in advance and I can check exact shipping for you.
