It was pretty straight forward, the kit come to find out after recieving my tracking #, was coming from china so there were no instructions. The only sketchy part was inserting the 3 pins into the supplied headlight connetor. Since there were no instructions i just had to guess until they turned on, and then switch them around until i got the hi low functions working properly. The way the high low works is the the bulb gets pulled back into the socket when the high beam is turned on and then extended into the reflector cap for low beam function. These ones have digital ballasts so mounting them out of the way was easy, i just used zip ties and the industrial grade adhesive zip tie bases to arrange the components around the head lamp area since both of my batteries need to be removed to acess the bulbs.
