Hey guys,


anyone purchase a plug and play harness from correy (jeep_addict) to use the DRL headlights on their jeep? I have a 2015 and have some issues. figured if anyone from the NYC metro or north jersey had an experience with this.

Thanks!

The problems im having varies. One minute the passenger side blinker works and then it doesnt. I can have the signal on and it'll flash for a few seconds then stop and drl comes on then it flashes again. a few minutes later it'll keep flashing and work as expected until i shut off the flasher.

the drl's and side markers dont dim/turn on when the headslights come on. The drl's stay bright and sidemarkers stay off. Sometimes the passneger side DRL/sidemarker works magically.

And sometimes either one or both DRL's cut out completely when the headlight is on and i use the turn signal. they are supposed to stay on (dimmed).

Are they brand new headlights? I've seen pictures of his harness but never personally installed one. I'm assuming it comes with resistors built in. Do you have any pictures of your install you can post and we can start eliminating some factors?

No high jack intended on this thread. My harness should be on its way in a week or so and I was wondering if anyone created a DIY on the install or even a video so people like me can follow along and do the install successfully?

I have one of his harnesses and had issues with the turn signals as well. The one side went on and worked for a few mins, the shut off and eventually I got the hyper flash and bulb out error. I was able to fix mine by increasing the load resistance on the turn signal wire. It should come with 3 ohm resistors. Try swapping them out with 6 ohms. It seems that some of these vehicles are a more picky than others. I ended up going with 2 Morimoto HD Load resistors in place of the 3 ohms ones included with his harness. That fixed my issue and haven't had another one since.

Still having an issue with the passenger side parking light wire getting tripped when the DRLs come on and the bcm cutting power to the parking light wire on passenger side. Have to pull it apart and do some more investigating.

Let me know if that works for you.

headlight switch is off...no E brake. If I get him start the truck turn the headlight switch on ..works fine ..if I turn the switch back off DRL's get bright.. then I turned it back on and the headlights came on no parking lights drls bright..don't dim after that ... hope it's something that can be worked out

Sounds like the same issue i am having. Once my DRL's come on, it causes the parking light circuit to lose power (BCM cuts it). Because there are not parking lights there is nothing to trigger the DRL module to turn off the DRL LEDs, resulting in the DRL's staying on. I have tested many many times and as long as I leave the headlight switch on, i don't have any issues. Once those DRL kick on, I lose my parking lights (passenger side only, which is what triggers the DRL module to turn off).

Check 1 more thing for me. Once this happens, turn on just your parking lights with the control manually and see if you have any parking lights at all. When the headlights are on with the bright DRL's, check the little orange marker on the side of the light to see if you can see 3 small LEDs lit (check both sides). If you don't see it on the passenger side only, you are in the same boat as me and I haven't worked out a fix... yet, but I will.


Once I cycle the engine, the BCM resets and the lights work again until the DRL's are triggered and turn on.

That is what Correy told me earlier when I talked to him. He mentioned something about it and thinks it may have be plugged in wrong and the cap was damaged. He also said something else about a ring terminal, but I wasn't sure what he was referring to, so I asked for clarification. Its really strange the the 15's were do picky about this because his harnesses have had zero issues with the 14's, 16's and 17's from what he said. I wonder what changed in them that causes so many issues with this mod?

I am going to test a few things out later tonight and if I hear back from Correy about what he was referring to, I will test that too. Worse case scenario, we could use a relay to drive both parking lights from the drivers side wire, but that means having to splice into his harness, which I would prefer not to do if I can avoid it.

Weird.... this morning I started the truck from the house like I do every morning... when I get outside I see the marker lights on. I hit the start button and the DRL's got bright.. instead of doing a power cycle , I just turned the headlight switch to on and wow it worked... dRL's dimmed with headlights

Was the switch in auto of the off position? If in off, switch to auto, let the DRLs come on then manually put switch in parking light mode and see if that trips it.

I suspect that there is some link between the cut out and the auto headlights when it turns on the DRLs

The DRLs should be on when the headlight switch is in the off position.

I put ONE inch heat shrink in the box the keep tension on the connection.


You can use Electrical tape or "zip ties" too, to get it fully seated.
 
#34 · (Edited)
Heat shrink was used, I just removed it for the picture so I could show the orientation of how it was plugged in. Do you think this connection is what is causing all of these issue? I can just cut it and solder/heat shrink the wires for a permanent fix if that is the case but since it can be working one minute and not the next, I'm not convinced it's an issue with the way this plug is seated.

I was just able to capture the issue, all sorts of weird stuff going on. The ignition cycle seems to correct the issue sometimes.

Take a look:

I'm having issues too! You know how in the beginning of the video you unlocked the car using the key fob? Well my DRL's on both sides don't come on. Just the headlights do and indicators flash to signal visually that I've unlocked the car. Anyone else having this issue? Also when I remote start the car driver side DRL turns on immediately and nothing on the passenger side for about 15 seconds. I've followed the instructions completely and even made sure to triple check before putting the car back together.

Though mine is a 15 and this probably the wrong thread, but ive got similar issues, so thought id throw it out there. Upon unlock via key fob or door handle, driver halo and headlight come on. passenger, only head light, no halo. Remote start also doing its thing with only driver side halo is on at half brightness upon start up immediately and 15 seconds and passenger comes on with driver when both go to full power. No headlights upon remote start, headlight dial in Auto position, daylight test conditions.

Funny thing is it did it last night, but was perfect this morning ( only headlights upon unlock tho, is that right or should it be with halos? And remote start was no lights for 15seconds upon start up then full power halos on both sides) Just tested again, these two came back. Have some other issues i put in my Appearance Enhancements 15 Altitude thread in visuals. Whats are the proper expected results for these scenarios?

I had my share of issues when it came to my lights. I went back and forth with Correy over 100 emails getting it worked out. I learned a lot and I know Correy is still busy making these harnesses, so I'm going to jump in here to help him. He was very generous with his time to me, so I'd like to repay him for that. Here are a few things for you guys to try to help isolate the problem.

1. Double and triple check all you connections, especially your grounds and socket connections.
2. Check you relay packs in the upper left corner of the engine bay. A lot of strange thing can happen if those relays get wet. Water will sit in them and make connections across terminal. To check, just pull the relays from their harness plug, put down a paper towel or cardboard and shake it at them. If it gets wet at all, you have water in them. They need to be completely dried out and I would suggest replaced. Then put back, sealed and installed so the harness and wires face down to prevent water from sitting in the open part of the plug.
3. I have helped a number of people with parking light issues, all were related to a bad cap. PM me if you have these issues so I can try to help you. I'd like to make sure this is the problem before suggesting you replace that cap (for those of you who are comfortable soldering).
4. If your DRLs are not turning off with your parking lights, please check to see if your passenger side marker lights come on (3 amber leds on side of light). If not, the parking lights aren't shutting them off which means the problem is likely the BCM shutting off the passenger side circuit. This could also indicate a bad cap.

If you need extra help you can PM me and I'll see what I can do.

Thanks!

Thanks for your help Jason, I really appreciate it!

I believe you are absolutely correct, I was able to get some 1000uF capacitors delivered today and did some testing with positive results. My harness came with 10000uf capacitors already installed but maybe one was damaged. I ended up wiring 2 of the 1000uf capacitors in parallel to replace the passenger side one and the lights work for the majority of the time but not perfect yet. I have new replacement 10000uf capacitors identical to the original ones in the mail along with a few others just in case so I'll see which ones work best. Do you know how the capacitance and ripple current affects the system?

Both of you, thank you for your responses. I will look into both.

I'm still a little confused where the harnesses you made go. What wires did you cut to wire in the female connector that these would plug into? Is it where I circled in this pic? Does it replace this? View attachment 140634

Correct, if you remove that cap, put the 9006 female connector and make the harness he posted, you can swap the cap out easily. However, I would encourage you to make sure the cap is really bad and that it's not just a poor connection at the bulb plug before going thru the modification. There are a lot of people that are having issues due to a poor connection (which can lead to the cap going bad).

3 things to check for:

1. make sure the connection for the turn signal from the truck to the harness is TIGHT. my right side would hyperflash/blink or stay constant, depending on how it felt. I secured the connection with electrical tape and zip ties. Problem solved.

2. I also strategically placed my grounds to where they got the best connection. Also scrubbed the metal POC (point of contact) where the grounds were laid, with a metal brush.

3. capacitors: Correy swapped mine out and my lights seem to be working accordingly. I bought a spare set of capacitors just in case. Stugots516 mentioned the capacitors that come installed (10000 uf) are overkill and that i should buy 4700uf, which i did but did not install yet. So im assuming after correy fixed my harness, he swapped out the capacitors with a lower uf.

Autostart- DRL's are dimmed and side markers on on.

Truck ON (DAY)- DRL's fully powered (bright) and cut out when the turn signals come on.

Truck ON (NIGHT) DRL's dim, HID's (lowbeam) and sidemarkers are on. DRL's stay powered on (dim) when turn signals come on.
