So i got a jenson headunit not to long ago for basicly free and now i just got my hand on a nice sub and amp and everything needed. Now i do have a decent backround with hooking car audio up but im having trouble with this headunit. Now i got a basic wiring harness from best buy with the speakers power acc ground ect. thinking it would work, idk see why it wouldnt i just know i wouldnt have the heads up display show things and the steering wheel controls and chimes wont work, and im fine with that. I wasnt going to spend 110$ on a wiring harness for those. So my question is, have people hooked up there system with this basic wiring harness? I got it all hooked up and the unit turns on but does nothing and plays nothing so is it my headunit thats bad or the wiring harness? 2004 grand pric comp g with monsoon
also another thing to note it came with a red ignition switch wire but had one on the harness already aswell, i hooked the one on harness to the one on the headunit. Do i need to splice in this other one and go to thefuse or power?
