I will get the codes off my car this weekend as I've been promising on this thread for awhile lol.

Thanks, I appreciate it.

Weird I didn't get a wiring harness with mine. I can't be the only one with this issue. My brother has a FORscan but I will have to wait for him when he comes to my house in December. Do you know the codes/process with your device to fix your issue?

Mine came with a harness. So far so good no issues.

Well mine did come with that harness but I am still having that issue.

I found a temporary work around where I just leave the fog lights one and they work fine.

Can someone please explain what the issue is with these lights? Im not clear on what people are experiencing and im not clear on what the forscan changes accomplish?

Sorry guys I seem to have lost my OBD2 reader so I can't check the codes. Looking over the spreadsheet and going by memory I am pretty sure this is what I changed. I will check if I find my reader.

BCM 726-45-01: xxxx 7Fxx xxxx (Allows Forscan DRL Changes)
BCM 726-26-02: x1xx xxxx xxxx (Enables Parking Lights as DRL)
BCM 726-50-01: 10xx (Enables dedicated LED DRL lights)

To get the OPT7's to be yellow in DRL mode, set 726-50-01 to 08xx.

See lines 25 and 26 on the Forscan codes spreadsheet: https://docs.google.com/spreadsheet...SN7v6AjN_t9rWvz0npQpcBbU_u0/edit#gid=53101868

Not everybody, but many people will have the DRL white light not come on during the day, and the sequential blinker will be scattered and random. At night they work okay. Using lights in "auto" mode may or may not be the culprit. The above Forscan changes the way the BCM operates so that the OPT7s work correctly. (White DRL day/night, working sequential blinker)

I believe that is the typical harness. I'm pretty sure mine looked like that as well.

Thanks for your help for that!

Thanks so much! Now to decide which to buy to give this a go!

For the poster that are having issues with the Opt7 lights give opt 7 a call and they will send you a harness that you plugin line with to the harness that goes from the module to inside the lights. You have to take the lights off and remove the two screws that hold the module on. Then pull the rubber plug out and disconnect the connector and place the new harness in line with the connector you disconnected. the feed the harness back in and reinsert the plug. The remount eh module and reinstall the lights.

I really shouldn't have to do that in the first place seems really redundant. Thanks for the tip though.

Not sure if this helps anyone. But I just installed my opt7 since purchased like 4 months ago and they operate what imo is correct.

 

[RaceRed5.0]

Mine only have the issue when the lights are off.

Race Red that is the issue I was having until Opt7 sent me the resistor harness. Here is a link to their install video . https://support.opt-7.com/143342-Special-Resistor-Install-2015-Ford-Mustang-Only This harness fixed my issue.

I bought my OPT7's in July and I just noticed that i am experiencing is the following... When my Parking lights or Headlights are on, the DRLs and Turn signals function as you would expect. However, when my lights are NOT on. Meaning the headlight dial is on the first, far left position, the DRLs are lit as expected, however, the passenger sides signal does the double sequential interruption to its-self. Video below. I'm tempted to try the forscan changes that were mentioned above, but i dont see how that would affect the situation im seeing. I dont see how any thing could changed for the turn signals functionality working as expected no matter if my lights are off or on. Opt7's warranty method is to send in the old part to get a replacement. Unfortunately I will not be dissembling the car for weeks to do that process.

Same issue here, only passenger side signal goes wonky.
