I post a thread before about my 99civic tail/plate light fuse kept blown(instant) for some reason. I read about checking on aftermarket headunit wires. I just checked all the wires for headunit and the taping also (wires seems all right, securely taped). After I put everything back and a new fuse, everything's going fine now, fuse didn't blow right away. I don't know where the exact problem is, and I also afraid it might blow again later on. Can anybody tell me what might cause the problem, so I can go check/fix and make sure it won't cause me another trouble.
By the way, if it's the ground wire, I have the headunit ground hooked on the factory ground wire on wire harness adaptor (the black wire) instead of hooking on the bolt behind headunit, don't know if that might cause the problem.


Thank you very much for you help!
