ULF28 and Ghosts

[07GD SFD]

I'm going to be re-wiring my car tomorrow and will be syncing all of my lights using a Whelen ULF28. I've got 2 EPI911 TIR3 lights in my grill, 2 Ghosts on my headliner, and 2 Whelen TIR3s on the B posts.


With the ULF28 flasher, do I need to run the white and black Ghost wires to the flasher's ground? Or can I ground them locally?


Attached is the ULF28 schematic.

Based on the schematic... I'd say grounds to the flasher... I haven't used the ULF 28... but my thought is if it gives you a ground for a light... it's for a reason...

Yeah I agree. That is a ground side flasher. If you ground your lights locally and run only 12v (+) then your lights will all steady burn.


That flasher is similar to a ground side traffic advisor controller. You could run one 12v (+) to all the lights (take into consideration wire guage) but each light needs it's own ground wire back to the flasher.

see if you can trade the ulf28 for a ulf44???

Thanks guys.


I ended up just running power and ground wires for each light. My lighting set up idea changed as the install progressed, but I'm happy with the outcome.
