Heavy wire
Real over kill for my 164 scooter, using it for a 4 in spal fan to help cool the engine.

Using this as fan bypass
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.

Simply the best.
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.

Mixed feelings.
I'm a bit mixed on this. The relay and harness are great and I would re-use that part. The included inline fuse however was complete junk, and failed and melted the entire case around it, almost costing me my engine.
