Those are the REAR Fog lights. You should have a switch on the left side of the steering wheel on the dash. I think it lights up green when it's on. Flip the switch then the back top lights should be on.

These lights, are just for better visibility in low visibility conditions.

I would like a diagram of the 740 gle 1990 tail light wiring, I cannot seem to get them working correctly


You don't really need a diagram, it's simple. If you open both tail light boxes in the trunk you will see at the connector on the bottom a yellow wire in the first position. That goes to the brake bulb. If both tail lights do not work, make sure you are getting power to the driver side light first, if it is not getting power, the passenger side will not work either, they are in line with each other. If it is only the passenger side not working, the bridging wire could be bad.. try jumping it. Also, make sure you are getting power inside the tail light bulb holder. The metal connections can come loose. If there is no power to the driver side tail light it could be the bulb failure relay, that is the round red relay in the rear left side of the fuse box behind the ash tray/ cigarette lighter below the radio in front of the shifter. You should be getting power to the third brake light in the rear window...that is a different circuit and will not be affected. Try changing out the bulb failure relay, it supplies the power to the tail lights.

Trailer Wiring Cheat Sheet


Hello all,

For those of you that have or occasionally borrow trailers and look at the wiring plugs with disdain (I mean face it they don't make sense, grd is white, +12vdc is black, etc), this is for you.

Plug Types/Application
7 Way - RV Trailers, Horse and Utility Trailers
6 Way - Horse, Stock and Utility
4 Way - Utility Trailers

Columns are: Color, Function, Mark on the plug.

Seven wire Trailer plugs:

Horse, stock or utility trailers:

White = Ground - 1
Blue = Electric Brakes - 2
Brown = Tail and clearance lights - 3
Black = Battery, aux power - 4
Yellow = Left turn/Brake - 5
Green = Right turn Brake - 6
Orange or Purple (not both) = Auxilliary or Reverse - 7

Recreational Vehicle:
White = Ground - 1
Blue = Electric Brakes - 2
Green = Tail and clearance lights - 3
Black = Battery, aux power - 4
Red = Left turn/Brake - 5
Brown = Right turn Brake - 6
Yellow = Auxilliary or Reverse - 7


Six wire trailer plugs:

Horse, stock or utility trailers:
White = Ground - GD
Yellow = Left turn/Brake -LT
Green = Right turn Brake -RT
Brown = Tail and clearance lights - TM
Red or Black (not both) = Battery, aux power - A
Blue = Electric Brakes - S

Recreational Vehicle: (color, use, plug mark)
White = Ground - GD
Yellow = Not used -
Brown = Right turn Brake - RT
Green = Tail and clearance lights -TM
Black = Battery, aux power - A
Red = Left turn/Brake - LT
Blue = Electric Brakes - S


Four wire plugs:
White = Ground
Yellow = Left turn/Brake
Green = Right turn Brake
Brown = Tail and clearance lights


Ground should be 10ga.
Others 14 ga

Best regards
Mike

What is the bulb number for the tail light brake light bulb for my 1990 Volvo GL Wagon? I tried 7528's and they work for brake but don't work for night light brake and tail light. Help! Your friend,...


Look at the socket? Are there two contacts? If so, 7528 (or 1157, same thing) is correct (and that's what the parts catalog will show). However, in the case of my 1991 740, there is only one contact in each socket. If that is the case use an 1156 bulb.
I spoke with an expert Volvo mechanic and he told be Volvo used two different tailight assemblies, a Hella and another one I can't recall by name. He said there appears to be no rhyme or reason as to what car has what, and this is the reason for the discrepancy in the proper bulb. The only way to know for sure what you have is a visual inspection on the unit.

Looking for a few things...


located where the ash tray is. Just below the ash tray compartment. Remove the ash tray' Then press down on the releae trim just below and a compartment pulls out. This gives access to fuses and relays located here.

For the owners manual, ebay is a good refernece for it and then would check with the dealership.

Looking for socket turn ligth


Those are Bosch sockets which Mercedes and Volvo loved, but which are a royal pain. The socket is a dual-filament socket  probably combining the tail light AND turn signal. The others are all single-filament sockets. They are NOT interchangeable. First determine whether the socket is really at fault. Sometimes the contact points don't quite connect with the long busses in the tail light assembly. I have successfully cleaned mine. Maybe you can reform the contacts to make better contact. If not,  Ebay has what you want under Volvo parts. The sockets for the 240 and 740 are the same, an d will fit either sedans or wagons. Voluparts in Atlanta Georgia has them too. Any junk yard with Volvos will have these sockets.  I bought a bunch of spares for $10
