14-UP Rear 720 and 400.4 Bridged Input
This "14-UP Rear 720 and 400.4 Bridged Input" is used on standard bikes with a rear 4-pin connector. This harness is used to split a Moto720 rear input with a SounDigital 400.4. This is typically used when you already have a SinisterSound Front kit and 6x9s but want to add on some Crazy 8s. Will not work with Ultra bikes or bikes using a SinisterSound breakout harness.
