THE MAIN FEED WIRE AND HORN RELAY-FLASHER FEED WIRE MAY HAVE BEEN CONNECTED IN REVERSE POSITIONS IN THE NUMBER TWO CIRCUIT BREAKER IN THE DRIVER"S CONTROL PANEL.
Remedy

The record is thin — 0 NHTSA complaints — so owner-report data can't strongly confirm reliability either way, though 1 recall should be verified as completed.
