What harness & ECM to use ???
What harness and ecm would make more sense I was looking for a 99-02 ls1 Camaro/firebird harness and ecm and then buy the adaptors for the 4l80. Or does it make more sense to buy like a Silverado 2500 that came with 6.0,4l80 harness and ecm,and just change the injector pigtails,or are these tuning limited ?
Hope this helps. If you need pieces or parts we sell those too.
