Power Up: The Morimoto 4Banger LED Pods have been developed from the ground up to set a new standard in their segment, and the same goes for the wiring. If you want the best, bingo. If you want cheap, you'll want to look for an alternative (and sadly, that wont be hard to find -- because until now, everybody has overlooked the importance of quality cables). OEM+: Not one component on the harness was overlooked for the sake of cost or simplicity. Triple sealed proprietary 4-pin relay with hanger. Proprietary over-molded inline fuse holder with 20A mini fuse. DT06-2S female outputs with dual seals. Stainless steel power and ground terminals. Proprietary M-Spec push button switch with Yellow-LED backlight. Proper: All wiring is properly sized and relays rated for flicker-free, reliable power delivery. Every line of the 16 awg copper wiring is protected with black mesh insulation. Every connector has been over-molded, sealed, or protected with heavy duty heat shrink. Your factory wire harness will fall apart before this thing. Plug n Play: The connections on the harness have been laid out in a logical way to power an LED pod on each side of your vehicle. There are two deutsch outputs. A positive battery terminal, and ground terminal, and a switch. The wiring for the in-cabin push button switch has an in-line barrel connector that drastically improves ease of installation, since you don't have to jam the switch mechanism through the firewall. Compatible: While this harness is a perfect match for the Morimoto 4Banger LED pods, you can make good use of it with any other off-road lighting setup that takes a DT-style two-pin input (which is basically the industry standard).
