Tail Light Extension & Auxiliary Power Harnesses


Categories: ,


Custom lengths are no problem just let me know what you need.

Use this harness when adding a longer than stock tail section.  Plugs in using factory connectors (this is a gen 1 Busa harness pictured).  It also has a 2 pin connector coming off it to provide auxiliary power and ground with key on to other device(s) through the tail light circuit.  Add a relay kit for more current capability for things like adding a fuse box.


Fusebox in photo is for reference only.  Wire sizing is currently 16 gauge with an automotive 30/40amp relay.


Contact me for custom lengths etc.

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.
