side marker lights on a P5
Ok I did a search and still didn't find my answer so here's my question....
I would like the side marker lights on my P5 to be turn signal lights, don't car if they light up as running lights, just want them to blink with the turn signals. Tried to wire them by hooking into the turn signal on the front but all I did was burn a fuse. Anybody else do this. I rewired the fogs to come on with the marker lights so I thought I could do this on my own but it is beyond me... Any advice.. Thanks in advance |
good question....I've also tried to turn the bumper lights into turn signals, but kept burning fuses...hope someone has an answer for this...

You're running too much off that one fuse. There's a way to rewire the fogs from inside the car so that they come on when the parking lights are on. Do a search and you'll find that. Once you take the fogs off that fuse, it will then handle the side marker lights. I re-wired my side markers to blink with the turn signals and it works great!

so what you are saying, hawkeye is to use the fogs servo for the blinks or what, could you give me a step by step as to what you did?
Much appreciated:D |
There is a guy on the MP5Online Yahoo group who re-wired the bumper lights to work like the turn signals (i.e. - flash with them). Should be the same procedure for the side markers - WARNING - this seems kinda complicated (but I have no experience woking with relays) - maybe take the instructions to someone with good electrical knowledge for explanaion and/or wiring help if you don't know what you're doing (like me!).
Okay. here goes. First off; If you are not familiar with car wiring and relays I would not attempt this. It can be tricky. Be sure to test all your leads to make sure they are right. I could include pics, but what would they accomplish besides showing an illuminated light... The way I wired my lights, I only used 2 relays (DPDT). Thats all I had lying around. Now with two relays, 1 per side, there are two configurations which seemed applicable to me. Since most wiring is at or near the light, I put the realy near the light in the fenderwell. 1st - Side marker operates normally with parking lights, and flashes with flasher. However, will not flash without parking lights on. (I usually drive with my parking/fog lights on so this is the configuration I used) 2nd - SIde marker operates normally, flashes if parking lights are not illuminated, and remains steady if parking lights are on. This means light will not flash at night. There are numerous other ways to wire these especially if you use two realys per side. Then you could make it work any way you want. But hey, I'm lazy and dont have any more relays. so: 1st configuration: DPDT relays are the 5 terminal type, listed with the numbers 85, 86, 87, 87a, 30. 85 & 87 - Connect to the ground wire at the side marker. (all black wire) 87a - snip the +12v wire approx 2" from the side marker(Grey or light green - forgot to mention I'm color blind). Connect the terminal to the switched side (not bulb side) 30 - Connect the bulb side of the lead to terminal 30. 86 - Run a lead from 86 terminal to the flasher lead at the front flasher (approx 15" of wire, it was the outermost lead with the white stripe on it). Connect it without clipping the lead to the flasher. Thats it. Check to see that the side lamp illuminates with the parking lights, and that it now flashes with the turn signal. 2nd configuration: All wiring the same except 87. Instead of grounding the 87 lead, connect it to a constant +12v source. I reccomend the terminal under the fuse panel cover under the hood. You will see where the battery connects to the block. WARNING!!!! Be sure to put inline fuses within 12" of the battery connection or you risk grounding out your battery. Fire, shorting, or nuclear wr could result in improperly protecting your circuits!!!! Good luck. I played with one side until I got it to work how I wanted, then wote down the instructions ans walked away for several hours. Once I had completely forgotten what I did, I went back and wired it according to my notes and it worked the same. So, there should be no problems. ~HH |
I believe the author of the thread I quoted above already tried a "direct" wiring scheme like the one in this link: http://lighting.mbz.org/tech/how_to/markerflash/
- but he said the fuse would continually blow - thus the need for making the modification with relays. I thought it would be simple enough to just tap into the wiring for the front turn signals/parking lights - but according to this guy, it con't be done that way on our cars. And adding a higher rated fuse to stop the stock one from blowing isn't a smart option. If somone tries to just "tap" into the wiring like in the link above, and is successful, definitely post your procedure and results. I hope someone does try it this way. And as far as all the work just for a flaching bumper light - well, some people (me included) think the non-flashing lamp is just silly. If it is there, why not have it blink, too? It's safer, and good-looking at the same time. I would not install the side markers, like the MP3 or 2002.5 P5, because I think that would look even worse - having the bumper light AND a fender light - even if only the fender light is illuminated - it just clutters up the side of the car, IMO. |
its possible I am just a moron and don't know what the f**k I'm doing. Plus I don't have a shop manual or a test lightto know what wire does what off of the turn signal/park lamp. If anybody knows what wire runs what or if I stop being a cheap bastard and either buy or make a test light maybe I'll try the link above. After I blew the fuse I stopped. I can't afford to screw up my daily runner.
The idea of the relays , although I appreciate the effort of the author , is beyond my skill and too involved. I'll keep you posted. peace |
Originally posted by TheMAN A relay is a very simple device actually. It is basically an electromagnetically controlled switch (it has a solenoid inside the box). Basically you have power source feeding through it. One is low draw and one is high. The low draw side is the one that will power the solenoid. When current flows through it, it will cause the solenoid inside to shut the switch allowing the high current side to flow. Very simple and allows for small control switches (the horn circuit, or the rear defroster button is one very simple example). when you have your park lights on your blinkers iny our head lights are on too but on a dim setting, when you have your hazards or turn signals on it will go to a brighter setting and flash. i want to have my side markers light up too when i have my park lights on but when i have my hazards or turn signals on i want them to get brighter too. i don't see how i can wire this since the relay can't control the voltage going to it. also one problem with the mechanical relay idea is that the solenoid will keep punching in and out to start and stop current from flowing. i would much rather have a solid state relay but those are way to expensive, ________ Jaguar mark viii picture |
This is not a relay or voltage issue.
The parking/turn siganles are dual filament bulbs. When the parking lights are on, only one filament is lit. When you put on the turn signal, the second filament is what flashes, making the lamp brighter. It's like two bulbs in one - not a matter of increasing the voltage. I re-wired my bumper lights to flash with the turn signals - all it takes is clipping the power wire for the bumper lights, and tapping into the power wire for the turn signals instead. Very simple, but the lights are not on with the parking lights - only as turn signals. To get them to do double-duty like the front lamps, you'd need a dual filament bulb and a three-wire socket to match. One wire is the common ground, the second would be for parking light power, and the third would light the second filament as a turn signal. The two power wires could be tapped into the power wires for the front lights with no problem. The issue is getting a dual filament socket and bulb that will fit in the bumper lights. Maybe something out there is a direct-fit, but I'm not sure - or maybe modding something to fit would be simple. But forget the whole relay/voltage increase issue. That's got nothing to do with the parking/turn signal lights. ~HH |
guys, how do you remove the fender lights in the first place? I'm afraid to try it... Thanks...

Hihosilva is right, just use dual filament bulbs. You can find the sockets at any auto parts store. They are universal and have metal "fingers" that hold it into place on the lens. When I get my P5 back from the dealer I'll look into it further for you guys. I'm pretty sure I can get it done without any relays.
|
Yep - it can definitely be done without relays by using a dual filament. Just a matter of splicing into the front parking lights.
I have my stock side bumper lamps flashing. If it winds up being that cheap and easy (to add a dual filament) I just might do it - I haven't looked into replacing the stock socket yet - now I think I will. ~HH |
LOOK AT ORGINAL POST.....TOO MUCH ON ONE FUSE......HE ALREADY REWIRED FOGS TO FUSE
LOOK AT ORGINAL POST.....TOO MUCH ON ONE FUSE......HE ALREADY REWIRED FOGS TO FUSE
SO HIS OPTIONS ARE PUT RELAY ON FOGS OR RELAY ON SIDE MARKERS. |
I got it to work very simply.
I got it to work very simply.
Cut the ground wire from the sidemarker bulb. Run a wire from the ground wire of the sidemarker bulb to the flashing wire of the turnsignal wire. Tape all connections and tape unused ground wire that was cut. :) :) :) :) :) :) :) :) :) :) :) :) :) :) :) :) |
