well guys i was looking through my toolbox on my 2500, and found a relay, wondering if i could use it to wire up a fan on my buddy's truck. it has a 87,86,85, and 30 under the prongs. its a 30 amp relay. it says ong chuan or something on top. 792-1A-Ca 12VDC 12V 30A


will it work for a fan? and how would i run the wires???

 

yeah it should if you know how to wire it up.
