im looking on ebay to buy a pc3 USB for my 06 engine. i think the part number is 312-411... the thing is that ive seen a couple of differ pics of the powercommanders but the owners say they are the same part #. one pics looks like it plugs into the injector harness and the other plugs into the ecm......just look at the pics and see if you can help me understand
