Where to Power

[Peco 10+ year member]

I think Starkfu is seeing what I was trying to say. I think I know where I'm going to run my ACC(ignition power) I was looking at where to get my consistent power, with out overloading (starting a FIRE) the consistent power on my factory wiring (radio) harness. So I want to run a 10 gauge wire from my battery with a 15a inline fuse (within 18" of wire from battery) to my HU and also run a 10 gauge ground to HU. Then I can connect the Camera and Navigation to the factory power wire. Should I ground the cam and nav. to factory ground or the new 10 gauge ground?? Also could I could I run everthing to the factory ACC (ignition power) or should I just use that for the radio and split the cam and nav. to the fuse box? FYI I will be connecting a amp to the HU so I cant use the amp remote wire on the HU.

well, the camera you are going to want to ground in the back (assuming it is a rear facing camera on the exterior). If the nav isn't going to be close to the HU, then I would ground it as short as possible (long ground wires are usually not a good thing).

I would connect all ignition wires to the one at the factory radio (powering three items off of this is ok, up to four items would be ok, otherwise you should use a relay).

You probably could get away with a 12 or 14 gauge cable for the HU power, but I usually use 10 gauge to the battery - fuse as close to the battery as possible.
