Hello. I bought a ls1 efan with a 3 relay nelson harness from a member here a few months back. they did a great job of marking the wires for me. my question is. they marked 2 wires one says to pin #42 the other says to AC green wire. Where will I find these wires so I can hook the fans up? Thanks in advance. I've tried the search but haven't found what I'm looking for. Yes I know I will need to go see my tuner before the fans will turn on.

 

Unplug the connectors from your PCM , look at the plug after removing it, it will have numbers on each slot.

You will need to pop of the clip on top of the connector that secures the wires to the connector.

Take a safety pin or similar object and push out the little rubber plug in the # 42 slot, then push in the new wire from your fan harness , making sure it clicks and looks even with the other pins. Put everything back together.

Then open up the wire loom from your AC compressor , your green wire should be in their if i remember correctley.

You can try blackbears site, he has great instructions, i bought my harness from him and it was super simple to hook up.

Good luck

 

Thanks . That's all I needed. I think I got it from here.
