Thats for those can can read and build a harness on their own though........easy for me to say I guess....
you're the man! thanks for all the effort.....looking forward to hear everything is still working flawlessly in two weeks!

They used these relays for controlling electric fans, a/c compressor, Air level compressor, horn, and electronic brake control modules, so the current draw these put on the system, if programmed correctly in the PCM to turn on correctly, they will not put a huge hit to the system....basically, stagger the turn on temps. And set it to the correct temp so that they cycle on and off while the vehicle is idling...a few mins on, a little off.

ok so i looked in hptuners and actually read what it said. and it has this enable disable speed thing. i thought it was just to turn the fans off when you reached a certain speed. but it also says that when a/c is on first stage fan when enable below this speed but not if coolant is hot. and the disable says will disable fans if a/c is on above this speed and if coolant is hot. so i may go for the 05 harness myself. mine works fine for now but my fans don't hardly even run hear in maine as cold as its been.

Played with the A/C a litle last night. It does not kick on the fans till it hits the set pressure, and it was about 50 degrees out so they never kicked on but once when I put a pice of cardboardin front of the condensor/radiator to make it warm up. Then it kicks the fan on, cause the a/c presure was high enough.
