misterp Posted April 16, 2007 Report Share Posted April 16, 2007 Call Nelson for the harness, I just installed my set about a month ago and used their harness...It's top notch.... Is the Nelson harness 3 relay, or 4? Do the fans have both a low & high speed, and does the harness also tie into the A/C? Mr. P. Link to comment Share on other sites More sharing options...

Mr. P, If you are using the defrost or AC, then one fan turns on high...If the engine reaches the preset rate with AC or defrost on, then both fans come on..If AC is off and engine reaches temp, then one fan turns on low....It's a 3 relay system, mount relays on the cover of the PCM, plug the fans in, insert wire into pcm connector and tap into the harness next to the alternator, and your done...

EmergencyVP1 Posted April 16, 2007 Report Share Posted April 16, 2007 i've been trying forever to find out how to put my 05 factory e fans on a manual switch. anybody got an idea for that? Do you want to disconnect them from the computer all together and only run them with the switch, or are you wanting to control them in conjunction with the computer?
