I am doing a 3 light mod on my 2000 magnum 500 . I have spliced all wires except the wire from # 87 on the relay. I have no lighter plug to go to splice into a positive wire to #87.
Thanks for any help anyone can give.

 

use pin #85 for ground, pin #30 wired to the low beams, use the high bean power wire and wire it to pin #86 and #87. #87a will have nothing wired to it. this will work since the low beams are isolated from the high beam. but when you turn on your high beam it will trigger the relay and allow power to go from pin 87 to pin 30 powering the low beams.
