I recently purchased a 1992 Honda Civic Hatchback VX. The guy had wired the headunits 12v constant directly to the battery because he said he was getting no power to the headunit otherwise. I tried hooking it up the other way and he was right, but i don't want to use a switch like he had for the headunit because if you turn it off you lose all your settings. I was wondering if theres any way to buy the entire wiring harness that goes from the headunit to wherever else it goes, and if i can how would i take out the old one and replace it, if theres any other reason it might not be working let me know that too. Thanks in advance
