Purchased this Integra recently and someone cut the pigtail at the front end. Looks like it was for the rad fan.

Anyone have a wiring diagram?

 

you might want to trace those wire to see were they lead to. im pretty sure that blue wire you see in the pictures is your fan wire.

the other wires that run around that area are, fog light harness, headlight harness, air bag/ SRS components, and your horn. i might be missing a few items to but that should help.
