fog lamp relay

Where is the foglamp relay located on an 87 xj/mj? My Comanche has the dashboard switch, but no lights. Switch is there, connected to the pigtail, and the pilot light comes on when I flip the switch on. Terminals A, B, and C have black, green, and black/green wires to them, respectively. If there's an existing relay, I'd like to use that for my rollbar lights. If not, I'll use an aux. Any ideas/suggestions?
Thanks

On my '88 MJ the fog light relay is attached to the radiator support frame, high on the driver's side (in front of the air box).
