Thread: E-Fan harness

  1. #1

    E-Fan harness

    I have two new e-fan harnesses, these are for 03-04 trucks but would work on almost any ls engine based vehicle. Duel pin style. $80 each

    Pictures added, harness is extra long to allow mounting flexibility. Relays are activated by ground, either connect to pcm or a toggle switch. Ground green wire and both fans come on at low speed, ground both and both fans will run high speed.

    What are the terminations? are these pinned to go into the ECU? And are they terminated for stock fans plug and play?

    Harness is pinned for pcm, has connectors for 2005-2013 truck fans, plug and play for automatic operation if pcm is tuned for efans. Can switch connector to LS1 F body fans if needed.
