Having problems with your 1989 Oldsmobile Eighty Eight Royale ?
Need to find the horn relay location on my 1998 Winnebago Adventurer with Ford F53 chassis
\015 R&R steering wheel and horn contact. Ohm check horn pad switch and horn contact. Both r OK. Ohm checked the 3 wire harness that runs down the steering column. All 3 wires r OK. Tested both horns directly with 12v. Both r OK. Disconnected 8 pin connector above horns to main harness. Tested with 12v. Wire is good to both horns. Need to find the horn relay to do further testing. Cannot locate in my chassis manual or on Winnebago's online wiring diagrams.\015
See the diagram attached.God bless you
