(Car is a VW Golf, 2000 Mk4)
I've been looking at the 'route' I need to take getting the power cable from the battery to the boot.
There doesn't seem to be an easy/accessible way to break through the engine bay into the body of the car.
However, under the steering wheel, there are a row of power feeds connecting to various bits and pieces.
Could I wire the power cable directly to this feed (with a fuse)? Or will it cause a problem? (If so, where/why?)
Thanks in advance,
Here's an easy way to get from the engine compartment to the cabin/trunk:
...at least that's what I did (had to run 4GA).
Whether or not you can connect to the terminals already there depends on what you're hooking up and what the rating is on the wires connecting the battery to the terminals.
But really, drilling a little hole in the underside/wheel well into the trunk isn't that big a deal. And you can run the wire under the car, so you don't have to mess with putting it behind panels or carpet. If you just do a small hole under the carpet in the trunk, you won't even be able to tell.
I'm not sure if this will work, but here's what I did...
I ran the power wire all the way to the back of my car via going under my car and pretty much followed the frame back. Then I punched a hole in the back, brought the wire up, and have my inverter back there. I figured it was the easiest way to accomplish it, took the least amount of hacking to my car, and only took like 30 mins to run.
On the other hand you have to make sure you have a wire that is capable of being run outside the car, and that handle water, rocks, dirt, etc...
I don't know much about wires, but the one I have is like a 4 guage, rubber coated one. It's heavy duty, and my electrician buddy said it is rated for outside conditions, corrosion resistant, etc...
It's lasted nearly two years without me having to touch it once. I'll be honest, I actually ghetto rigged it when I installed it. I only used those zip cord things to secure it to my frame. I should probably check it to make sure none of them broke, came loose, etc...
But nonetheless it works great. Just make sure you have a cable.
I just used a big drill bit to get through the underside of the trunk. They have metal drilling bits (carbide tips) that work well. It's pretty much the fastest method, and you won't have to tear apart your interior to run the line through the car.Originally Posted by VanMan69
So long as you put some split-loom cable covering and keep it away from the exhaust manifold (had mine a little too close and the split loom started to melt a bit), it should be alright.Originally Posted by SnyperBob
I'd recommend adding some split-loom to your 4GA... it will also help protect against friction/abrasion between the cable and the frame. You don't want it to rub through and short to the frame.

I screwed a 8 gauge wire onto the 30A terminal. It worked fine for about 2 years. I'm adding a amp for a subwoofer though so I ran a 4g wire directly from the battery terminal. Running the wire was easy. I found a spot that had a little rubber grommet plug. I took out the plug out and put the wire through.
I managed to run heavy duty 3 core mains flex on my old company golf (MK4 estate) from the battery to an inverter under the front passenger seat. from what i remember (i dont have the car ay more as i quit tha job) there is a bunble of cable that runs into an extruded gromet on the right hand side of the engine bay and about half way up the fire wall. its not easy to fit the cable through but it will go
