71 K5 factory a/c 350 /350 CST, the question I have is, in the engine bay on the firewall left of the power brake unit iare 2 relays, factory installed looking and no stereo,lights,extra stuff

what do they control ?

the horn is inside by the fuse box and the fan relay on the passenger side of the AC behind the glove box.
