Kindly please send email to kaslight2@outlook.com, we will send you the manual accordingly **Q: Will this work on an 87 toyota pickup ?** A: I installed it on my 88 Toyota pickup 2wd. The high beam did not work. The high beam relay would work but would not turn the high beam on. Found the wiring on load side of the relay was wired wrong so I had to pull the wires out and relocate them. High and low work good now. If the relays work, but won't turn the lights on, the issue is on the load side. Check the wiring on the relays. **Q: Will this work on a 93 chevy blazer if not what harness would?** A: I dont know alot about Chevy blazer but work great in my 93 XJ. I dont see why not, ## Frequently Bought Together - KASLIGHT 1Set 2 Headlight Wiring Harness H4 Relay Harness H6054 LED Headlight Connector Socket Kit for 9003 6054 Toyota 95-97 Tacoma 88-95 Pickup Headlamp Fix Dual Light Dim Dual Ground Problem - HWSTAR 2022 180W 1000% Bright H6054 5x7 7x6 Led Headlights Compatible with Jeep Cherokee XJ Wrangler YJ [ DOT][Anti-glare][DRL Turn Signal][Hi/Low Sealed Beam] Ford Chevy GMC Toyota Nissan Dodge etc --- ## 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.tn/products/256037056-toyota-headlight-relay-h4-harness-kit-1set-2-h6054-wiring](https://www.desertcart.tn/products/256037056-toyota-headlight-relay-h4-harness-kit-1set-2-h6054-wiring) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-28*
