Nathan @ XSpower Posted August 24, 2010 Report Share Posted August 24, 2010 Yes, when you purchase the harnesses for the alts it is just plug and play basically. First thing you need to do is get all three alts working without the VCM hooked up, and then hook up the VCM. You cant use the VCM harness to power the other alternators. The VCM harness will only hook up the alternators to the VCM so it can control the voltage. Quote Link to comment Share on other sites More sharing options...
