just picked up my 2015 nismo and I want to do this. but the more I read, the more confused I get. am I basically splicing the red and beige wire together and pluging it into another slot?

yes. It's really that simple.

its simple but the pictures aren't clear and im not the best person with wires. TRUST ME! even I can F this up.

I'm all set to do this tomorrow, let's see how it goes...:eekdance:

Can you connect it to any of those four ports? Or does it have to be the one in the top right corner?
Also how do you get this cover off?

ah.. I got it! it didn't take me 30 minutes though because I had problems taking the prongs out. but it looks great with it on all the time. should've came like this in the first place.

How did you take them out? I don't want to break anything and I don't want to cut the cables either...

I removed the white plastic from the back. From there, I acutually ended up cutting the wires then pulled it out from the bottom. It doesn't matter if you cut them because you have to add more wire to it to run it to the terminal anyways.

Ok, thanks! One question for all who have done this or know about the electronic layout of the car, Can I just leave everything the way it is and just strip a little bit of the red and beige cables and run the extension to the relay? Leaving them connected and all, can that cause damage or overload something? I don't know...

Done! Took the cables out with the connectors. No cutting or stripping wires, just joined the connectors with the extra piece of wire and done.

I always wanted this functionality, glad I found this thread. Trickiest part was removing the pins from the connector since there is a very small plastic clasp that holds them in place. I had to cut the size of the blade on the spade connector to fit into the relay, hopefully I won't have a problem with it popping out.

Has anyone done this on one with nav? My nav display would not turn to the night time mode as the DRL always on. I believe the nav display turns dark when the DRL is off(when the headlights are on). I'd have to manually change the display to 'dark'.....

Does this mod turn the tail/side marker lights on with the engine too? I did the modification from IJDMTOY, and now when the engine starts the DRL's are on like normal but the taillights and side marker lights are illuminated too.

Just thought I would add a quick addendum for anyone else doing this mod.

The electrical connector that worked for me was a 1/4" however I needed to file 1/16th off for it to fit snugly in the fuse box. I'll update if it loosens up. I think it will be okay though because it requires needle nose pliers to remove from the relay port.

Exactly what I did, although I filed from all directions :icon17: and the trouble I went through to get it in, I don't think it's gonna come loose anytime soon. That's the way it should've came from the beginning! Looks sick :tiphat:

Before i do this mod will it affect the auto dim of my nav?

No it will not. The DRL is a simple circuit.

I did this months ago in a hotel parking lot and my tool kit. Easy peasy.

MMine came loose but it was my fault. I used a slighly to small spade connector. Redid it and actually did the same thing you did jammed it in and its been steady for months.

I love this mod! Thx for the how to, OP!!

I (finally) did this, thanks for the DRL DIY!

I pulled the DRL connecter out and managed to get it apart and still yanked the tan wire off the pin so I'd recommend you just cut the tan and red wires 2-3" up from the plug and just leave the ends stuffed down plug empty sockets (like the red one below) so if it needed to be reversed you could just strip the end then and twist (solder if you're a pro) them back together

Was very quick once sure had proper red / tan wires (other reds and tans had light silver stripes on them) just focus on the plug lower right in my pic and you'll be fine

you definitely need the bladed plug to plug into the "on when engine on" source, no way to connect the wire just jamming it in there (not from lack of trying) but, luckily, since I'm a garage hoarder I dug into my electronics box-o-crap and found a match.

Went very quick so detailed the engine bay as I reassembled.
Thanks again!

Cool. Will do this in April or May once the snow has melted, the salt is washed off the roads and the Z is outta storage.

Does anyone know if this works on the 2015 Nismo??

Yes. It's the same car as a non nismo minus a few exterior mods and exhaust. It will work just fine.

Thank you for this! I've been wanting to do this with my Z I just bought, but I didn't know the size of the spade connector. :tiphat:

Great write up. Did it on my 2015 Nismo

Finally did this mod works awesome thank you!!!!:bowrofl:

Finished this mod this evening. Hardest part was getting the connector to fit.

Sorry for my big stupid ignorance. But how the heck do I do this? Read the whole 5 pages and I'm so confused.

So get to the box
Find the red and baige wires
Cut each in half? Then what?

Sorry need a step by step picture guide. Anybody want to help a wiring noob? I wish there would be a video or a step by step detailed guide.

So, most people cut the wires, I didn't. I took my time and opened the connector and with a small (very small) flat head screwdriver took out the red and beige wires with their connectors. Tied the two together with some 18 gauge wire (I think) and the other end to a flat connector and stuck it in the plug. cover everything with electrical tape or plastic covers.

This is very simple to do...like 30 mins of your life perhaps a hour if you never have.

Essentially your cutting the two wires involved with DRL in IPDM box which is essentially a wiring junction box. Nissan for whatever reason created a complicated circuit that determines when your DRL are on or off. Kinda of puzzling since usually a engineer takes the easiest path for design.

You first step should be disconnecting the battery.

Find the two wires that provide power and ground to the DRL..the guides on this site point them out. When you cut them you will have 2 loose wires and the two stubs that are plugged in. For myself I just electrical taped wrapped the ends that are still plugged in.

You you need to remove some of the wire's insulation. You can do this with a tool designed for that or use like a razor blade. Twist the wires together then insert them into a spade connector.

Your DRL require 12 volts and there happens to be a 12 volt port with nothing in it. You take your spade connector and put into that slot. Thats it. Its simple.

Probably the hardest part is finding that spade connector that will stay in that slot. The one I had was slightly to wide so I trimmed it down some and inserted it.

Easy peasy.

Well, here's a question for the automotive wiring geniuses. I like the idea of wiring the DRL so that they stay on when the headlights are on … and it seems like a pretty simple wiring job based on the above DIYs. However, is there a simple way to wire the DRL so that they stay on with the low beams, but turn off with the high beams (… much like front fog lights typically do)?

Not with that method. You would have to design the circuit to do that which would require some doing. The method described above bypasses Nissan's circuit and applies a continious 12volts to the LEDs while the car is on. The two are independent.

Thank you for the pics! I so get it now :rofl2:



Thanks for the explanation. Will definitely do this later today! :happydance:

Today was the day. Finally completed it. Thanks for the instructions.

Thanks 370zlvr, your route was the easiest way to do it!

Here are some additional pictures.

I just bought a 2016 nismo and I'm looking to do this mod but I'm not even going to attempt doing it myself would just feel more comfortable paying someone that knows what there doing to do it for me. Was wondering what would be considered an acceptable quote for a job like this?

I've been looking for a way to shut the DRL's off during the day or just have control of them for that matter....for my safety they say...:wtf: I wonder if this mod plus a switch would do the trick???

$10.

I just wired mine to a switch last weekend using this write up

Oh man. I really like that switch setup.
