I'm looking for a detailed page showing the relay positions for a 1989 Gl 740 (non=turbo) sedan.
I had an electrical fire caused by a faulty light relay. I've changed the fuse box but need to have a good reference for the relays and the positions and the wiring for them, also the wiring for the standard radio and the equalizer as well.
Appreciate any help on this. Thanks.

(ID letters are from the diagram greenbook)

Back Row:
• "A" Bulb failure warning sensor
• "B" Seat belt reminder/key warning
• "C" Windshield wiper intermittent relay
• "D" Tailgate wiper intermittent relay

Middle Row:
• "E" Fuel injection
• "F" Foglights, front (USA/CDN)
• "G" Headlight flasher
• "H" Exhaust temp sensor (Japan)
• "I" Overdrive

Front row, left to right
• "J" Overload relay, power windows/seat heater)
• "K" Headlight
• "L" Central lock
• "M" Rear fog light (not USA, Canada)
• "N" Overload relay high beam (not USA, Canada)
