## Description

Spal Fan Harness With Relay (40 Amp)

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