Hi, new to the forum.
My son is working on putting a new head unit into his 2012 accord lx-s coupe. He pulled the factory unit out and now the new one won't turn on.
1. We bought a scosche wiring harness and validated all the wiring is correct from the harness to the new radio. We also checked it is connected securely with no bent pins.
2. I got my test light out and can see power both with the ignition flipped and without on the constant (white) wire on the factory plug but get nothing on the switched (violet) wire both with the ignition flipped (I should see current when the key is turned) and without. Also, both his cigarette lighters are no longer working. This tells me the aftermarket harness is not the issue but something straight from the car now.
3. I tried hooking up the factory radio back and the security light is on but it won't power up either.
4. I checked all the "accessory" fuses on the driver, passenger, and under the hood areas but all are good.
I've done a far amount of car audio in the past but I don't know what else to check on the car.
He tells me he disconnected all the plugs carefully while he was taking everything apart and getting the radio out. I don't think he disconnected the battery on the car while he was doing this so I'm wondering if there is some other fuse (maybe labeled with an odd name) or a relay I can check.
The owner's manual isn't a ton of help....this is no differentiation for the radio.
Any help is appreciated.
