Power wire on fan got burnt up in the fuse box and decided to run an external relay. It comes with instructions and high quality parts to get the job done. I bypassed the PCM and grounded it so the fan comes on with accessory. Great kit for a good price. Review: Worked great for a manual fan switch - Worked perfectly for what I needed. I soldered it directly into my original fan connector and added a manual fan switch for my Mustang. Everything needed was included in the kit, and I just paired it with a simple switch from AutoZone. Solid setup and did exactly what I wanted it to do. ## Features - Fit type: Universal Fit - Package Dimensions: 19.812 H x 7.366 L x 14.224 W (centimeters) - Country of Origin : China - Package Weight: 0.748 kilograms ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B003PB4AY8 | | Best Sellers Rank | #125,349 in Automotive ( See Top 100 in Automotive ) #490 in Automotive Replacement Electrical Wiring Harnesses | | Brand Name | Spal | | Color | Regular | | Customer Reviews | 4.7 4.7 out of 5 stars (273) | | Date First Available | June 3, 2010 | | Included Components | Spal Fan Harness With Relay (40 Amp) | | Item Package Dimensions L x W x H | 6.65 x 5.51 x 2.28 inches | | Item Weight | 1.2 Pounds | | Manufacturer | Spal | | Material | Plastic | | Model Name | Spal Fan Harness With Relay (40 Amp) | | Number of Items | 1 | | Package Weight | 0.64 Kilograms | | Part Number | FRH | | Size | No Size | | Suggested Users | unisex-adult | | Warranty Description | Warranty | ## Images ![Spal Fan Harness With Relay (40 Amp) - Image 1](https://m.media-amazon.com/images/I/818JxuWJcQL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Using this as fan bypass *by E***C on November 5, 2024* Used this kit to cure a common problem on s197 Mustangs.

Solid setup and did exactly what I wanted it to do. ### ⭐⭐⭐⭐⭐ Simply the best. *by D***R on June 10, 2021* As some other people have said this harness is everything you need and of great quality. I was really surprised when I unboxed this harness. Everything is of the highest quality right down to lettering on all the wires to make sure each one is identifiable. I was also surprised to see how long the power wires were for the battery and the fans. I expected maybe five feet but I was amazed as I rolled out ten feet of wire. I ended up cutting off so much that I was able to use it for two other projects. Every connector and terminal was included as well. I would recommend this product to anyone who needs to use a fan relay on their next project. ## Frequently Bought Together - Spal Fan Harness With Relay (40 Amp) - Fan Mounting Kit, Mellbree 2-Pack Electric Radiator Fan Mounting Kit Compatible for Electric Cooling Fan and Transmission Cooler - Spal 30102049 16" Curved Blade Performance Fan , 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.co.th/products/10284244-spal-fan-harness-with-relay-40-amp](https://www.desertcart.co.th/products/10284244-spal-fan-harness-with-relay-40-amp) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-05-16*
