  • Specific Opus wiring question

    I'm about ready to install my carputer and ran into a little problem. Well, it's not so much a problem, as it is a lack of knowledge. I'm trying to figure out how to wire my Opus 150W power supply into my 2002 pontiac sunfire. I'm a little mixed up as to where to hook up the 'ignition' wire. I've read through a lot of posts but nothing to help out my specific question. Everyone says it hooks into the ACC. I've got a link that'll tell you what wire does what for my car. Can anyone tell me what color wire to hook into?

      Heres what I did. I bought a fuse tap from autozone. $6 and used the fuse for the car stereo. Works like charm! If you need a picture let me know.

        neat drawing, makes things much easier to understand

        18 gauge?? i thougth you everyone was saying use 8 gauge OR was there somewhere else you were suppose to use an 8 gauge. Mine is going to be going from the trunk to the battery in the front (approx. 15 ft after going through carpet).

        yes please post pictures, it would be helpful.

          Make things easy on yourself and tap the 12v wire into the red wire running down the steering column and the ACC to the orange one that will be there as well. Then just ground it back in the trunk. Use a ring terminal like the one in the picture and clean the spot you screw it to very well. The wires will be 12-14 gauge under the dash. Use 14 gauge wires to run from the Opus to the wires under the dash. There should be fuses on both the 12v and the ACC wire. They are both live the whole time your is running and the 12v will be live all of the time, car off or not. People in here try to make this harder than it really is. I was a car stereo and alarm installer and we used these wires many times for our remote starts. Do not forget the fuses!!! They will protect your car in the event that you should accidentally ground one of those live wires or if the insulation should ever get worn and the wire comes through and grounds out.

            Why does everyone ground to the car? I ground to the negative terminal and it works great (Opus manual tells you to do this.)

              Shortest path to ground is always the best practice.

                That made a HUGE difference for RFI when i was playing with my temporary rig. Infact it made an FM modulator worth thinking about.
