Hi all, I need to run 8 gauge wire (two wires) through the firewall, on the driver's side. Anyone find a good place to run it? Pic to give you an idea of wire thickness.
I know (I spent a bunch of years as a cook, many decades ago). I was testing the extremes. It's billed as a true dual zone fridge/fridge or freezer/fridge (or vice versa) or freezer/freezer, so, I wanted to see how well it handled both extremes. 30° is the highest it goes and I figured -4° is a good deep freeze that matches my household freezer. I haven't used it yet (on a trip or anything)... testing before it's in the desert, 2,000 miles from home, in May.You only need 0° and 37° for food safety and not freezing eggs, dairy, water etc. You have good margin especially if you put in foods and drinks that are already cooled.
I found this, which is interesting, and perhaps helpful. When it's not pouring out (tomorrow evening, maybe), I will check it out.Usual good practice is to run a ground wire up toward the battery and connect it to the same point where the battery connects to the chassis rather than to the battery's negative terminal. These keeps the ground of your system equal to chassis ground irrespective of voltage drop on the batteries negative lead. This is also better than relying on a ground path through the chassis as there are many panels and joints in uni-bodies.
I ran 2 10ga stranded wires (twin lead) for my transceiver through the hood release grommet. I used a fiberglass "fish tape", pushing it from inside the cabin to the fender well, where it was easily retrievable. I tied the 10ga twin lead to the end of the fish tape, and pulled them all back into the cabin, to underneath the passenger seat. Took about 15 minutes. BTW, do not connect the negative lead directly to the battery. There is a current sensor there. Instead, use the ground lug near the strut nut next to the battery. You can see my installation, with three NMO mounts, elsewhere on the site.
I ran a similar sized power cable for my Ham Radio installation. I ran the wire through the hole where the hood release cable gets routed into the engine compartment. Here is a thread that discusses that effort:
