i need a diagram for yhe relay to my cooling fan on my 68' iroc. any help would be appreciated. i got a new relay and harness and the wires are not color coated and when i got the car there wasnt one on it so i dont know wich wires go where.

Well if they even made a 68 Iroc i might be able to help u but since Iroc didnt come out in 68 i cant help u
