Yup that's the correct one. Odd that it's not coming on though. Unfortunately Ford might be the best place to ask at this point. Other than NoLimit's issue with the fuse (which it doesn't seem to be) I can't think of much else that would make it not work - it's a pretty basic connection, and you seem to have tested about everything you could.
2020+ FPIU Headlight Wig Wag Patterns
- Thread starter SEPD_52
- Start date
I’ve built a crap load of these cars, and never had them not work. With the other quality issues that Ive seen in these cars, Im not at all surprised though. If it were me,(I had this same problem on 2 or 3 cars) my next steps would be pulling all of the fuses related to headlights, but I think it was the high beam fuse that worked for me. Then reinstalling, to see if that fixes it. If that doesn’t work, Id disconnect the battery for a bit. If that still doesn’t fix it, Id be scouring the car looking for pinched or broken wires. That wigwag wire probably only goes from that plug to the bcm, so it shouldn’t be too difficult to find.

Did you get this figured out? I just had another one do this. The highbeam indicator on the dash was working, but the actual highbeams weren’t. And the wig-wags were not working. I removed this fuse, then re-installed it, and everything works now.

Id say that I see it about once in every 20-30 cars. Maybe a coincidence, but this last car had a master power switch. So you can run the lights with the ignition off. Maybe it has something to do with activating the wigwags while the ignition is off? This car also had the DRLs that you can’t turn off. I don’t know if that played a part in it?
Sorry for the delay
The issue ended up being the "tester" I was using did not move enough current to activate the wig wag function........
When I used a proper wire it worked fine, so it was all user error. Thanks for everyone's help
Can someone please post the triple flash pattern for these? Had no idea the WWs had flash pattern options
Just for the sake of conversation does anybody know the pattern and set up for 2017 FIPU I have a guy that has one that's asking for it he can't seem to get his pattern out...
I believe the 2020 model year was the first year the headlight flasher was factory. So on the 2017 there could be multiple different flashers that were used.
Correct. Pre 2020 it was not built in to the BCM. If you got factory wig-wags, it was a Whelen flasher module. The module was a little white box on the passenger side behind the headlight. It’s been awhile since Ive done one, but I believe the activation and pattern wires are in the center dash with all the other upfitter wires. Im pretty sure all the info is in the upfitter guide.
Thanks guys I'll let him know that that's what he should be looking for instead of thinking he should be programming something into the BCM..
