SpalFan Harness With Relay (40 Amp)

Used this kit to cure a common problem on s197 Mustangs. 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.

Very nice quality wiring harness…plenty of length and a complete package.

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.

Incredibly well-built product at a good price. I have a SPAL VA10-AP50/C-61A 12" puller fan in a '72 Saab 96 and this was the perfect way to adapt a modern fan to my old car. Derale, Hayden, and others offer similar products but pale in comparison in regards to build quality. Loads of wire included, the yellow and red wires are somewhere just north of 12 AWG (wires are metric, it's an Italian product) and the grey and orange wires are roughly 18 AWG. I had some initial fuse issues and SPAL's customer service was out of this world. An actual engineer responded to my lengthy e-mail of specifics with laboratory results in PDF documents detailing inrush currents, wire temperature ratings, etc. Take your time, crimp well, use shrink tubing, and follow the instructions. You can't go wrong with SPAL.

Works as intended

Put a pair of these in place of a Volvo fan controller for a set of Dodge Intrepid fans on my recent V8 swap into an S10. They work MUCH better than the Volvo controller, with less wiring. I am running one for the low and one for the high circuit, both controlling a pair of fans at their relevant output. I've had no problems at all, HIGHLY recommend these for your aftermarket cooling solutions.

Usually I prefer to made my own relay harness by myself to be sure I will install perfect and high quality wire and correct gauge, and because I don’t trust market harness.. but I bought one set of spal harness to check it quality.. Honestly I was shocked how it’s awesome quality and perfect made..!! I believe I wist my time and money to made my old harness.. so this is my third order to replace All my old relay harness with spal relay harness.. so I bought 7 sets..!!

I purchased this wiring harness to control power to an electric auxiliary fan for my A/C condenser in my truck. The kit includes just about everything you’ll need:RelayWiring HarnessInline 30 and 40 Amp fuseFan pigtailElectric crimp connectorsThe relay is excellent quality and has a waterproof quick connect plug for the wiring harness. The provided wires are very thick and great quality. Even the provided electrical crimp connects are nice and are the heat shrink style. I highly recommend this kit to everyone.
