And I am not the only one complaining that I purchased the wrong part for my vehicle, based on Amazon's assurance that is the right one. Hope this helps. **Q: Will these actually fit a 2014 Nissan Titan Pro 4x? I have bought some that said they fit my truck but they do not.** A: Prob not bud I found the same issue and never received a refund but they stated they would fit I purchased them for a 2002 Durango slt and they did not so I will advise to check for yourself the pins and the voltage or amps and make sure they match regardless of what Amazon says . Because they don’t know anything and this continues to happen …. **Q: Do these things last long? Or do they keep blowing and thats why they send 4 of them?** A: So far so good with mine. They live in the toolbox with the battery on the tongue of my trailer which sits outside. ## Frequently Bought Together - BLAU GRUN 4 Pin 12V 30A Multi-Purpose Automotive Relay - Heavy Duty Standard Relay for Car Motor, Universal Replacement Accessory - JOREST 300Pcs Car Fuse Assortment Kit, 160 Mini Blade Fuses Automotive + 90 Standard Auto Fuses + 50 Micro + 1 Puller – for RV Camper Boat Accessories (2Amp 3A 5A 7.5A 10A 15A 20A 25A 30A 35A 40A) - Jeseny 2 Pack Car 5 Pin 12V 30A Relay - High Performance Waterproof Stable Multi-Purpose Heavy Duty Standard Kit for Automotive Motor Replacement Accessories (Black) --- ## 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/531078479-4-pin-12v-30a-multi-purpose-automotive-relay-heavy-duty](https://www.desertcart.tn/products/531078479-4-pin-12v-30a-multi-purpose-automotive-relay-heavy-duty) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-29*
