So i wouldnt be able to just remove the head unit, get the wiring harness for my model, connect the two sides and plug the rca cables into the ports and be done?

The head unit also only has 2 rca ports on it while the wiring harness has 4 rca cables, so if anyone knows an easy solution it would be very helpful because i'm new to this. Thanks again

Would anyone be able to give me in-depth instructions on how to install a single din sony aftermarket stereo. Im not looking to alter anything besides the head unit. This would be very helpful. Thanks
