I have a 2015 camaro SS I purchased at an auction it was vandalized and motor and transmission was removed. I purchased a complete motor and transmission installed it and I had to replace the wiring harness under the dash from another car. I got everything hooked up and installed battery went to turn ignition switch on and nothing. I checked the battery power good 12v check under the hood at battery post 12v have 12v at fuse block under hood have voltage going down to alternator and starter. I have power at the rear fuse block. I don’t have power on the fuse block under the dash. But my mirrors have power. F1and F25 has no power and the fuse marked bat has no power
