12 Volt Plug and Play Power Accessory Harness


Category: SKU: N/A


If you are tired of hacking into your Hayabusa’s wiring harness trying to find key on power and ground for accessory items up near the dash or in the tail section this product is for you.  This accessory harness plugs into the “Euro” connector on US Hayabusa’s near the right turn signal and provide 12 volt key on power and ground to (1) item near the dash and (2) items in the tail section.  I supply the mating connector and pins for an easy, clean installation.


This works great on 99-07 Hayabusas.  For 08 Hayabusas it will still work but does require that you REMOVE the gauges to access the connector to plug in.  Currently your running lights next to the head light are plugged into this circuit, just unplug one of them and plug this harness inline.

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.
