Took all of an hour or so. My 1969 F100's headlights started to blink off after being on for an hour.

If so which side?** A: The black connector plugs into the female wiring socket that you removed from one of the headlights. The two yellow male terminals get plugged into the back of headlights. You will have to install the black connector into the headlight harness on the side nearest the battery. Mount the relays, battery feed and that side's ground strap in the same area. The long extension to the other headlight gets into the back of the headlight after you removed the terminal. Install that side's ground. That original female terminal that was on that headlight will no longer be used. Tape it up and secure out of the way. **Q: Does this work with a 1986 Toyota pickup?** A: Yes it does I have it on my 88 4runner **Q: Does this work on 2004 honda crv?** A: Probably don’t need it. This is for very old vehicles that Cannot regulate the amperage to the LEDs. If your LED lamps flicker when you install them, this should solve it though....... I think. **Q: Will this relay kit work on a 1992 Dodge D-250 Diesel?** A: Sorry, the fitment said not fit your car. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Easy Install. *by D***H on 28 May 2026* Easy install.
