Headlight relays

I used a couple of relays on my 1971 Dart GT. I used the original wiring to enable my relays (see schematic), but did NOT damage the original wiring. I simply found male terminals that fit the original headlamp sockets and plugged them in as if it were the headlamp. I then drilled a small hole on the passenger side fender and mounted my relays (near the A/C drier bottle).
