You will be placing your relay and fuse in this wire.[*]Find a good location to mount the relay along the path of the power wire.[*]Cut the power wire at the relay.[*]Connect the side of the power wire that comes from the light fixture to pin 87 of the SPST(single-pole, single-throw) automotive relay.[*]Attach the other side of the power wire that runs toward the battery to pin 30 of the relay.[*]On the battery side of the wire from pin 30, attach a fuse holder.[*]Attach the other side of the fuse holder to the battery positive.[*]Connect the ground wire from the fixture directly to the battery ground. So now the power wire should be coming from the battery to one side of the fuse holder, out of the other side of the fuse holder to pin 30 of the relay, and out from pin 87 of the relay to the light fixture positive. The ground wire goes directly from the battery ground to the fixture. You have now completed the load side of the install. All that is left is the control circuit. Control Circuit[*]Run a wire from pin 85 to the location inside the tub of your switch.[*]Connect it to one side of the switch.[*]Run a wire from the other side of the switch to the nearest ground lug in the tub.[*]Connect pin 86 of the relay to 12V power source (either switched or unswitched, depending on your needs). This completes the installation.
