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 ### ⭐⭐⭐⭐⭐ Great product *by J***E on 17 August 2025* ### ⭐ Rusted and sparks *by M***K on 13 March 2022* ### ⭐⭐⭐⭐⭐ Great item. *by G***Y on 4 November 2020* ## Frequently Bought Together - Partsam 1Set H4 Headlight Relay Harness Kit for 7x6 5x7 H6054 Headlights Heat Ceramic Wiring Harness Compatible with Pickup Headlights 88-95, Tacoma 95-97 Fix Dual Ground Problem - Partsam 2PCS Rectangle H6054 LED Headlights 5x7 7x6 Headlamp Hi/Low Sealed Beam H4 9003 Plug 6054 H5054 Compatible with S10 Blazer Express Van/Wrangler YJ XJ Cherokee Truck Van - Partsam H4 9003 HB2 Wire Wiring Harness Sockets for 4"x6" 7"x6" 5"x7" inch Sealed Beam Car Truck Headlights Pickup Heavy Duty Headlamp (2PCS) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.th/products/527244982-1set-h4-headlight-relay-harness-kit-for-7x6-5x7-h6054](https://www.desertcart.co.th/products/527244982-1set-h4-headlight-relay-harness-kit-for-7x6-5x7-h6054) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-06-06*
