Where is the flasher unit on a 1993 Isuzu located?
From Haynes Repair Manual for Ford Ranger Pickups 1993 - 2005: " (1)Disconnect the negative cable from the battery; (2)The flasher relay for 1993 and 1994 models is located on the interior fuse panel; on 1995 and later models it's under the instrument panel to the right of the steering column. Remove the flasher by pulling it out. (3) Install the new flasher unit. Press flasher firmly into place". Good luck.
