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.
