Not a hard job or complicated but could be hazardous. Hire a professional.
It would depend on what system is fitted
eBay or your local auto electrician.
take it back to the guy who put the stereo in and complain.
You may be disappointed to find out that your Dell Inspiron 4150 was fitted with a MONO microphone input jack.
yes if you have fitted an after market stereo and used the live off the flasher to run the stereo,try disconnecting the stereo to see if they stop if not you could have a faulty switch.
If it is the original factory fitted radio take the model and serial number to your dealership with your VIN. They should be able to tell you the code.
is this on the stereo/head unit? if there's no visible socket its proberly on the rear of it, which means taking it out :(
On 1984-1989 Corvette, the dash top grilles only housed speakers if the car was not fitted with Bose stereo, about 10% of production. TOM
squeeze it a little bit with a pair of pliers until it fits snugly in the socket.
you need to swap the ignition live with the permanent live just unpick the clips and swap them job done
The OEM radio (the one that comes fitted - Original Equipment Manufacturer) has a 2 wire 'data output' to the centre display (using the I2c communication protocol) your new stereo won't have this data output, so, you loose any ability to communicate with the display note, some head units CAN talk to the display, check your exact model number for details, you often need to buy an additional cable
Next to the tube socket on the chassis the tube number is stamped.
