How's it going. My name is Nick and currently my girlfriend had purchased a 90 honda civic lx but the factory headunit that was in it needed a code. Instead of going through trying to get the code I bought her a headunit. I got a harness adaptor that connects to the headunit's harness; however, when everything is hooked up nothing happens. I tripled checked with both wire diagrams to make sure everything was right, it was. One thing that throws me off is that the memory back up wire it's 7.5 amps BUT the powerwire is only .5 amps.. Can anybody point me in the right direction on what to do? Thanks!
