I have recently installed a new double din or tried too ..... it has power but will not turn on fully when testing the red (ignition) no power on the new harness end.. but on the factory harness I have power.. but here is my question I’m going off the two red and gray wires as the ignition on off maybe I’m wrong because they are showing power even with the key off ?? Am I using the wrong wires? Thanks for any help
