This harness plugs into your original fan power wire on an AGT K model, LRT 23 or similar machine with a 14" SPAL cooling fan and creates a dedicated direct-wire 25+ amp circuit for your main and accessory fans.

The in-line relay isolates and prevents accessory cooling fans from back-feeding power on shutdown.

The plugs used for the relay switch and main fan will match the plugs on K models and LRT (possibly others).

The accessory fan connections are common 2 pin waterproof automotive plugs.

This harness was designed to be used with one brushless 2900 CFM  ProForm 67035 14" puller fan, or could be used with the original and one 10" or two 7-8" auxiliary fans. Note, using this harness reverses the original fan rotation to pull instead of push. 

Be mindful of the Rato 739cc's 25 amp max charging capacity when installing additional cooling fans.
