I have an EP3. Ive been asking about this on EPHatch.com but really didnt get much help. Ive searched EPHatch.com and ClubRSX.com and tried a few things others have but all I get is blown fuses. Im trying to get my sidemarkers to stay on with the parking and head lights but still blink normally.Ive tried running a test wire from the green/yellow stripe wire going to the sidemarker to the red/yellow stripe wire going to the parking light. The sidemarker lit up with the parking light but the turn signals did not work at all. Someone suggested a relay but Im not that familiar with electrical and have no idea about what relay to get or how to wire it. Help. What do I need to do?

 

Um, you're going to have to rig up some sort of XOR gate type of thing. Look up a circuit diagram on that. This way, when the parking light is on, it'll invert the signal from the turn signal, so the end result will be what you're looking for.

 

I think I might have to take a couple of classes in electrical/computer engineering before I try that one. Anything simpler?

 

Use a relay... Just run the power wire from your parking lights to the positive side of the sidemarker through the <U>Normally Closed </U>part of the relay.

Run the original sidemarker power wire to turn on the relay so it opens the circuit and blinks the sidemarker.

This is just an idea I came up with when I read your post so it's not tested but I'm almost sure it will work.

The only thing that may be weird would be the speed of the blinker but that's just a hypothesis...

Try it out and post back how it works...

 

Thank you. So do I just ask for a normally closed relay? Are there different kinds? Would 87a be the kind of relay I should ask for? How many prongs? I found this image online. Would you be able to tell me how to wire it using this image cause Im still a little unsure.

The problem with your idea is that it provides no provision for blinking when the parking lights are off, unless you run the power both through the relay AND through the regular power to the light, in which case you'll need a second relay to disengage the blinker's connection to the bulb when the parking lights are on. Either way, you'll need at least two relays or a XOR gate.

The simplest way to do it would be to fit a twin-filment bulb in there or drill a hole for a second bulb, and just have the parking lights turn that one on separately.

 

Good call, I forgot about when the parking lights were off... I drew up a new schematic on a piece of paper that will work with the parking lights on or off now.


Yes. The relay pic you posted is the right kind but you're going to need 2 of them to make it work.

Tonight I'll draw up a picture of the schematic for wiring them up and post it.

 

what was this i heard about a false ground? tap the parking light and tap the turn signal as the ground?

 

Alright here's the schematic with 2 relays. I used the picture of the relay that was previously provided to draw the schematic so you should be able to look at that picture to figure out the relays in my drawing.



here's the schematic

 

So I need to use 2 relays per side? What is going on at the 85's? And on the right side of the sidemarker in the drawing?

 

The uneven lines are ground at the 85s and the sidemarker. You can use 2 relays for both sides or 2 relays per side it just depends on how much wiring you want to do.

If you only use 2 relays then just run double the wires.

 

Alright let me get this right, I should do the following:

Splice into the signal wire of the sidemarker and run a new wire into 87a on the first relay.

Splice the new wire just made and run a new wire to 30.

Then splice into the signal wire of the parking light with new wire and run it to 86.

Then splice the new wire just made and make another new wire and run it to 87a on the second relay.

Run a new wire from 87 on the first relay to 86 on the second relay.

Then splice into the signal wire of the blinker and run a new wire to 30.

Is that right so far I hope?

Im still not sure about the 85's and the other side of the sidemarker. You said they are grounds. What do I need to do with them as far as wiring?

 

By grounds I mean they are negative... the sidemarker already had a negative or it wouldn't light up... as for the 85s on the relay you can just ground them to the chassis somewhere.

If you run all the wires exactly how I have them then it should work fine.

 

Thanks to you and everyone for trying to help me out with this so far.
I went to get some relays today and the guy quoted me $12 a pop. And they werent even Bosch. I was like "what!" I thought they were a couple of dollars at most. So if I were to use four, thats like $50 dollars just for relays. Im looking for something more cost effiecent. What if I run a wire from the signal wire on the sidemarker to the signal wire on the parking light and run a dual filament bulb (maybe LED) in the sidemarker?
Do you think that would work?

 

I have mine on costant w/ it blinking when i hit the hazards or Turn signals. I dont exactly know what was done since my cousin did it. But ill ask him, you dont have to buy anything because everything works fine and I didnt need to purchase anything Relays etc. It only took 20 min. Ill ask him and let u know

 

1 relay per side. 85 ground, 86 +turn signal input, 30 ign(power when key is on only), 87A output to light. Cut the factory wire that is providing the hot or power and run the wire from 87A in its place. Use a SPDT(single pole double throw) relay.

Could you explain that with a little more detail. Im stupid when it comes to electrical. Specifically what to do with the 85 and 30. What about the 87(not A)?
