Yeah, I have both beams, from both lamps. My kit didnt need ANY additional power or ground connections. Each bulb socket connected to a mid-harness, then to the ballast. The ballast connected to the capsule, and the high-beam lead connected to the solenoid base.
OP, what color temp did you get for your MIL? Older people tend to have difficulty with night vision, and it's worse at the blue end of the color spectrum. It's best to stick with a warm 4300K color temp. Your pics look to be around 6000K, as compared to the other lights in the image.
I chose 6000K but it does appear more blue compared to my 55watt system. Hmm, I will contact the seller and have them send me 5000K and 4300K
