having trouble finding a spot to run a power cable throught the fired wall of a 97 oldsmobile cutlass supreme
Normally, when I do systems, I run it through the hole in the firewall, that was factory drilled for the antenna wire. Unfortunately, I dont think the antenna in this car is located up front, so. People run wires through the door. I personally don't like this, because you can see.. My personal opinion, would be to drill a hole on the passenger side, underneath the dash,and fill the gaps with silicone and run your wires down the side of the door, pushed under the plastic.
Your fuse panel might desire to be interior the automobile, and you will pull a cord off the fuse block (fuse section, no longer battery section). If no longer, you could pull a warm cord off the cigarette lighter. some autos, like my spouse's Honda, have the lighter on switched voltage (turn the biggest off and the lighter is going ineffective).
