  • Using same gauge wire when running to a switch.

    If Im placing a toggle switch in the middle of the red power wire than runs into the opus. I think that wire is like 8 gauge. Do I need to also use 8 gauge wire to run to the toggle switch?

    Or could I get away with like 10 or 12 guage?

    wire need to be the all the same from power source to ground. the weak point in the system must be the fuse, not the wire. otherwise you risk a fire.

    although 10guage should be enough for a computer...what amperage are you running.

      put the switch on the remote line not the main power line

        I had wrong figures. the wire going into OPUS is 14 guage.

        xd, putting it on the remote doesnt work, because when my computer freezes or shuts down for any unknown reason, Ive had a switch on the remote and it doesnt work.

            it's not a bad idea to put a switch on the power line either. i have a switch on my main power. my PSU even when turned off still draws 250mA. i'd rather have a switch to make sure it draws 0mA.

              well drawing power isn't a bad thing, since it'll keep your computer on standby. besides, the opus would shut off this whole thing before the voltage reaches below 11 volts right? so you'd still be able to start the car...

                not talking about keeping on standby. talking about full shutdown. even when shutdown, motherboard still draw power for such things as keyboard wakeup or wake on lan or stuff like that. it's never totally off.

                  dont run a 14 guage go with a 8 or 10 14 is going to be toooooooooo small


                  putting a switch on the remote line should work becasue ur going to cut the remote power to the pc causing the opus to shut down after the certin time frame u set it at or u can tap into ur 2 pin switch on ur mobo and extend it to ur dash with a momentary switch
