Needsdecaf Posted July 21, 2006 Report Share Posted July 21, 2006 Doug:I remember reading this thread before I purchased the R, and had kind of forgotten about it until recent posts on SS about programming reminded me of it. Now that I am more familliar with the R and have done some wrenching, I would like to attempt this mod. However, in reading your instructions and looking at the following picutres you posted:I'm a little confused. The wire harnesses you purchased seem to have lots of wires but you only speak of cutting the pink wire.Could you do a step by step to spell it out a little better? Sorry for the lame post, but I'm not super experienced electrically...although I did manage to hardwire my V1 and my Sirius radio correctly on the first try! Thanks...if you want to do through pm's, that's great too. Joe Link to comment Share on other sites More sharing options...

defgh1 Posted July 21, 2006 Author Report Share Posted July 21, 2006 First, I must make a disclaimer. Volvo likes to change the color of their wires each model year. My instructions are for the 2004 V70R and the 2005 and 2006 may have different color wires performing the same function. With that said, you need to find the main 12v voltage High Beam lead going to each headlight (purple for the 2004) and the 12v switched connection going to the fog lights (pink for 2004). The harness for the 12v relay has 5 wires. First thing you do is splice the yellow wire to the white wire and then splice both of them to the main high beam line. I used a fused link between the main and the yellow and white wire relay connection. Connect the black wire to a good ground. Now you need to find the switched lead going to the fog lights. There are two leads going to the fog light, one is the switched side and the other is the ground side. On my car pink was the switched lead and pink/white was the ground side. You then cut the switched lead in half and connect one end to the red wire and the other end to the blue wire. I used a longer piece of double connector wire to attach these wires to the relay harness wires. If you get the fog light wires incorrect it will not work and you will then need to splice the wire you cut back together and cut the other one for the connection to the relay . Do the driver's side first since there is room to work under the car. Once you get that side working then duplicate the same on the passenger side. In operation the circuit allows you to use the fogs normally with or without the low beams by using the dash switch. However, whenever you activate the high beams, either in flash mode or full on, the fogs also activate. If you want to have car inspected or take it in for service, just pull the fuses on the added fuse link and everything is back to normal.Doug H Link to comment Share on other sites More sharing options...
Needsdecaf Posted July 22, 2006 Report Share Posted July 22, 2006 First off: Alex, man, that was a hell of a lot of research! Amazing amount of stuff you've learned there. Terrific! Ok, Doug, thanks for the education. First off I have an '04, October '03 build date so hopefully the wires are the same color! I think I am slowly starting to catch on. The 5 wires on the harness are yellow, white, red, blue and black. When you say splice the yellow and white together, I'm assuming that you used the quick splice to splice the yellow wire to the white, then hooked the white to the pink main wire using the fused link as a splice. Sound about right?Ok, I think I shouldn't have any problem finding the pink and pink / white wires coming from the fogs. But the red wire? Which one of those harnesses up above has the red wire, is there only one coming off of the main headlights? Keep in mind, I haven't really poked around looking for this stuff, so please excuse me if it is obvious where to find it! Finally, where did you stow the relay and fused link, up top by the headlight harness? I'm assuming by your parts list that the wires that come with the harness are not long enough to reach down to the fog light wires, hence the wire and butt splice, correct?Again, thanks for the help and pardon the relatively inexperienced questions.Finally, I have tried to adjust my fog lights in the past. The adjustment knob (white plastic) is very difficult to turn and I couldn't really get the fogs to move that much. I actually broke off the end of the knob adjusting them. Can I pop them out of the holder and give them a good spritz of lubricant to make 'em move better?Thanks! Link to comment Share on other sites More sharing options...

But the red wire? Which one of those harnesses up above has the red wire, is there only one coming off of the main headlights? See the photos on page one for the location of the "Purple" main line. Follow the harness going to the headlight and you will see the purple wire to splice into. The red wire is part of the relay harness and is connected using a longer piece of wire to one end of the pink fog wire you cut in halfKeep in mind, I haven't really poked around looking for this stuff, so please excuse me if it is obvious where to find it!

You can remove them to see why they are binding up. Just be careful with any lubricant around the bulb surface.Thanks! Link to comment Share on other sites More sharing options...
Needsdecaf Posted July 22, 2006 Report Share Posted July 22, 2006 Ok, did some poking around. There are three wires leading to some kind of connector on the back of the headlight assembly (right behind the white adjustment screw). One purple, one striped, one black.Assuming this is the wire?

defgh1 Posted July 22, 2006 Author Report Share Posted July 22, 2006 No, you are looking for a 4 wire connector with purple(violet), white, gray, and black wires.Doug H Link to comment Share on other sites More sharing options...

Ready to R1568908309 Posted July 23, 2006 Report Share Posted July 23, 2006 Ok, saw that one! Thanks Doug.Hey guys,You can make your fogs work independently of high or low beam activation with a download of the "non-US fogs". Some dealers may say "it is illegal in the US", but it really is not. It is illegal in many states to have more than four lights burning on the front of the vehicle, and since most cars have 4 bulb high beams, they cannot legally activate the fogs with the high beams. The R's bi-xenon's high beam, however, is achieved by rotating the single bulb on each side, so one can turn on the fogs and only have 4 bulbs burning.The result is the same as Doug's (except the fogs do not energize when flashing high beams. If you have turned them on they stay on) without any rewiring required. Of course you have to install the Silverstars to achieve the identical results.

Needsdecaf Posted July 23, 2006 Report Share Posted July 23, 2006 Well, the only problem with this is trying to get your dealer to download it for you. When I print out the alignment specs from VADIS and bring them to my dealer, their response is that I shouldn't be reading stuff on the internet, and they aren't Volvo specs. I can't imagine what I would hear if I asked them to do this. If you can, that's great.
