dkahns51 Posted July 16, 2011 Report Share Posted July 16, 2011 Ok so im down to my last wires.. they are all black grounds. 2 are coming from the harness 1 with a terminal, 1 with out a terminal. 1 is coming from the head unit harness and it has a terminal on it. also the previous head unit was grounded to a wire that was black/blue stripe that is not from the harness but next to it coming out of a group of wires. So my question is.... Can i take the terminal off the Head unit harness ground, and use a butt connecter and ground it to the harness ground and then just tape off the other ground on harness that has a terminal?

dkahns51 Posted July 16, 2011 Author Report Share Posted July 16, 2011 (edited) The Half ring terminal is From the head unit harness The full ring terminal is from Harness the regular ground wire is from Harness The last picture is the black and blue wire that the previous head unit ground was hooked up to. The previous harness that was in car before did not have a ground on it...

zx10intn Posted July 16, 2011 Report Share Posted July 16, 2011 the ring terminals are meant to provide a high quality ground, find a solid spot behind the HU and place them there Quote 1969 Chevy Chevelle 20/22" staggered Bonspeed Huntingtons wrapped in Nitto INVO's Mechman 250amp cs144 alt w/AVBM Kinetik 1800 main battery/Kinetik 2400 in the trunk Pioneer AVH-3200dvd Headunit (2) sets of Hybrid Audio Technologies Imagine components up front (2) DD 3512's d4 coils Sundown sax100.4 component amp Sundown saz-3000d subwoofer amp 5ft^3 box tuned to 34hz MY BUILD Link to comment Share on other sites More sharing options...

jmilch Posted July 16, 2011 Report Share Posted July 16, 2011 I dunno how to fit a drill in there lol. You can run those ground wires wherever you need to. Just cut them and extend them 8-10" and use a quality connector and CLEAN the surface you make the ground on. If you use the factory ground wire you may have a round loop noise that is prevalent on that pioneer unit. I have the big brother P4300DVD and because of the way the RCA's are situated, I had ground loop issues with mid/high amp. I made a new solid ground, and whala the problem was fixed. THe dimmer line needs to go to your factory harness if you had a dimmer wire on it. Not all cars have this. Check your wiring diagram online to see if your car had a dimmer wire in the stock harness. If you do not, just do not use the dimmer wire. Do not ground it out.
