To the best of my knowledge (and according to my 97 shop manual) it is on the left frame rail under the battery - behind the air filter. Here's what the manual says. Sorry, no pictures.
CAUTION: The radiator fan relay is attached to the
left frame rail near the lower radiator support. The
relay bracket, and fastener are used to dissipate
heat from the relay. Ensure the relay is properly
attached to prevent the following:
˛ Intermittent engine overheating.
˛ Relay “thermal” shutdown, or relay damage.
Hope this helps.
