Fast355 thanks for your quick response and yes I am using the 7730 ECM I'm not a wire guru by any means but what did you mean by "The 2nd fan output is on the same connector directly opposite the 1st output." I had the efan harness made by a friend of mine and he assures me that (in the pic) the blue and green wire's need to be pinned to the connectors that connect to the ECM he built the harness according to the wire diagram in my last post. Here's a pic of the harness he built for me it has 3 relays 2 fan pigtail connectors ground and pos connection and the 2 wires that connect to the ECM connector my question is where in the connector do they connect? Thanks
