| I have look at just about all the post on dual cooling fans, maybe I am slow but none of them are helping me at this point. If somebody could let me know what I need to do I would be really thankful. I will even post pics with this because I am truly lost! 1. My primary fan only comes on when I do a diagnostic test and with a paperclip. Fan works at no other time. Seconadary fan has never come on since I bought the car. I have bought a Hayden 3647 with the hopes to just bypass everything and have both of my fans come on at 200 and off at 180. I have installed the Hayden 3647 and mounted the temp probe. 2. I have no idea of what wires to cut or what relay to use. The instructions sould like greek to me. I have what appears to be two relays coming off the fan wiring harness, I believe that all black one "see pics" is the primary and the black and white one "see pics is the seconardy" there is also a thrid connector " see pics" and I have no idea what it is or does but some of the wires from both relays are running to it. Can anyone tell me a real simple way of what wires to cut and hook to my Hayden 3647. So my fans will work. I live in the south and I can drive my new toy because she over heats in traffic, no problem on the highway. pics 1 and 2 are the relays and the thrid pic is a connector that has wires from bout relays going to it?????????????????? | | | |
