Installed EVO-GMT1 to my 2011 chevy equinox using install guide " Stand Alone installation with T-harness guide". Programmed module per the guide. Used Dcryptor per Guide, module lights were as on the guide. programming went good and dcryptor went well as well. When connecting module back to vehicle, data-link first than every other connection, notice that when connecting the data-link no ligts came on, in the module, so just went ahead and try to start vehicle nothing. vehicle did not even try to start. also no lights came on in the module. try to start vehicle with key and also nothing. removed t-harnes and module from vehicle and vehicle started fine. reseted module to factory setting and redid all programming that is required and still have the same issue as above. vehicle wont start hitting 3x lock or using key. the only way it starts is if i remove everything from vehicle.
p.s i only removed module and left T-harness and still vehicle wont start with the key. it will only start if i remove T-harness and module. what could be going wrong?
