    I just installed a trd pro grill and some raptor lights on my second gen Tacoma.

    Everything works well while it’s running but it has a weird quirk of intermittently turning on for what seems to be like short instances then turning off while the truck is turned off.

    I have it on the EFI fuse since I want it running even when the headlights are off. I’ve seen other Toyota forums talking about EFI fuses drawing power when the vehicle is off but haven’t seen anything about it here. Should I just move it to a different fuse or is there a simple fix I’m missing?

    Yes. Tapping off the EFI fuse is the issue. The truck uses the fuse when it runs the evap test. Run a trigger wire from inside the cab to the engine bay. Connect it to a fused relay and then to your lights. There are 3 or 4 holes in the firewall you can run wires through.
