a switch that i flick every time i turn on my car. i used a nissan relay. it is a very basic easy set-up.



if you do do it like the way i have make sure you turn on the fan, or else heat time.

 

a NEW fiero fan or a 20+ year old used one?



I have a Koyo for my S5 TII conversion, will the S4 fan shroud fit it?



Guess I could go look later when it stops raining if the S4 and S5 shrouds are interchangable
