Do those have any extra harness or just the small red box it comes with.

OPT7 has all the hardware necessary.
Their kits come with a driver, a capacitor, and a polarity switch. All of which are individual cables and can use whichever you do or don't want/need.
Personally I used nothing but the driver on my high beams(9005 is OE - no flicker and ran great without switch and capacitor), while I had to use both the polarity switch(wouldn't turn on without it) and the capacitor(flickered without it), for the low beams(H11 is OE).
Working with them has been fantastic. I've been extremely happy with their products on my build.
