Not sure what a 1993 LT35 E is but
do a "eliminate them" process!
door open with key in ignition will have a buzzing relay
with ign on activate the left or right turn signal will have a clicking
relay.
another relay may activate glow plugs IF it is still plugged in and you turn
the ign on, so now you have a 50/50 chance of finding it by pulling one or
the other out before you turn ign on!
does that leave the last relay?
Some have a relay for delayed wipers too!
Horn relay should click if the horn button is pressed and the ign is on.
