[QUOTE="jwarren808, post: 8242852, member: 633428"] i'm installing my first head unit and wanted to make sure i'm covering everything, not leaving anything out? my car is a 1990 Honda CRX Si, a couple years ago my car was broken into and they stole my head unit and my amps and they cut the factory stereo harness plug off. someone on the12volt forum pointed me towards the correct harnesses i needed for my car, so i got a metra 70-1720 harness adapter and a meta 71-1720 reverse wiring harness, and the new head unit i got is a Pioneer DEH-150MP. i don't have amps or subs, its just going to be a head unit and 4 6.5" coaxial speakers in the stock locations, so nothing complicated. i understand how to install the head unit, and am sure i can do it, but i just wanted to mainly cover some things before starting, just to make sure i understand everything correctly and am not forgetting anything ? my first question is, since they cut my harness when stealing my last stereo, what things do i need to check that would be affected from that happening?, like any fuses blow? i should replace before starting install? or any other things to check ? do i need to put a ground wire from the back of head unit to the body of the car ? on the new head unit i got? or not? or is that only to get rid of ground noise problems? theres a blue wire with white stripe coming from the pioneer head units harness and its labelled "system remote control", but the blue wire on the harness adapter and reverse wiring harness i got are labelled "power antenna", is that the same thing? or not? also, theres an orange wire with a white stripe called "dimmer", coming from the harness adapter but there is'nt an orange wire on the pioneer wiring harness? so where would that orange wire connect to? any help with these questions, would be appreciated, thanks [/QUOTE]
