Welcome to Just Commodores, a site specifically designed for all people who share the same passion as yourself.
Yes I have done it you have to use the Vy plug and join into the Vx harness speedo/tach ect are all the same serial data. If its a ls1 you will need to put a Vy powertrain interface module in otherwise you will have engine light problems, and for v6 it should be fine because they don't have a PIM, the only problems I had where the mode buttons not working properly and when I turned the ignition on it came up with alarm activated by passengers door and by Hotwire. Could of been cause I was using a sedan cluster in a ute I don't know I think you can disable it in the cluster engineering mode anyway. Also fuel guage reading opersite just need to put a Vy fuel sender in
Yes everything worked, yeah you blew a fuse, 10a red in drivers fuse box
