pardon the dumb question, but is the relay just wired in series between the
switch and the light?
+++++++++++++++++++++++++++++++++++++++++++++++++++++++
The relay is not in series with the head light. Think of the relay as the device being turned "on" instead of your head light bulb. the relay will have a coil that makes it work in it, marked plus(+) & minus(-). the "hot" (+) wire that comes from your handlebar switch That used to go to your headlight goes to the + terminal on the relay, the - terminal is connected to a GOOD GROUND on the frame. Now when you use the handle bar switch you will be opening (light off) or closing (light on) the relay. The relay is nothing more than a heavyier duty switch. Now run # 14 gage wire ( with a 20 Amp fuseholder in line) from your + terminal on your battery to the relay and connect it to the terminal marked N.O. (normaly open). From the terminal on the relay marked "load", go to the head light. make sure that the grounds on your bike are good. If you did everything right, when you turn on your head light with the handlebar switch,you will be energizing the relay, which will close its mu!
ch larger contacts allow the hea
dlight to draw its power through the 14 gage wire, across the large contacts in the relay, and to the headlight. This should result in less voltage drop at the headlight and brighter light.
Good luck
