Custom Wiring Job on 2008 G6 Sedan aftermarket headunit
Good Day Gents,
I am new to the site and would greatly appreciate any assistance yinz can offer. Firstly, i'm aware that i can buy and adapter for for OEM wire harness for my head unit. I Do not want to do that as that is an absolute last ditch effort. I already cut the harness of the harness, I have wired my chinese 7" touch screen double DIN unit (mostly) correct as when it does power up, it works fine, speakers, bluetooth, radio, you name it. Trouble is i cant locate and acceptable accessory power source for ignition. I Tried wiring the accessory power from the head unit to the brown wire on the ignition switch....that didnt go so well. Sometimes the car wouldnt start and when it did my all my gauges didn't work. So next i tried to wire to the passenger fuse box with a fuse wire adapter. When wiring into ANYTHING i was getting mixed results, all of which didnt suit me. I'd wire into the wind sheild wipers (which are IGN switched) and my wipers wouldnt work. Id then try wirirng to a blank fuse area or my on star (battery powered, i know stupid...) and the car wouldnt start. Basically every IGN fuse id wire to either refuse to power the head unit or start the car or kill that feature......i have a multimeter, ive tested the fuses and the wiring. everything is good on that front. Now, the only thing i can think of, is to run it to the accessory/cig lighter fuse in the trunk......only problem with that is the cig lighter in my car is always hot (battery powered) so in theory, based on what ive already seen, my car wont start....if it kills my cig lighter, i wouldnt care, any thoughts gents?
