So my brother has really wanted to move the battery in his 300SD to the trunk and we had been looking around in the yards trying to find a good cable. As you may know, many late model Mercedes and BMWs have super long positive cables running from the trunk to under the hood but we found that those were rather difficult to pull. Well put together interiors plus electric seats made it impossible to pull in the yard in a reasonable amount of time.

Fortunately we found the perfect vehicle to pull one from: Chevy Cobalt/Pontiac G5/Pursuit. Very common in the yards. They have huge, high quality (surprising) cables that stretch the length of the car and are very easy to pull. All you have to do is unbolt it at the power distribution box under the hood and remove the driver's seat and rear seat bottom. The rest is just ripping it out. Since GM interior quality, especially in the mid 2000s, is utter crap, ripping up the carpet and other panels is easy enough. Took less than 20 minutes to grab two.

The cable also has a thinner wire that plugs into a maxi fuse holder with a 50 AMP fuse. Great for a wire to an amp or something else with a similarly high draw.

Since our big local yards are Pull-A-Parts (3 in Atlanta), all battery cables, no matter the length, are $4. A 50 AMP Maxi fuse alone costs $5. Didn't measure it but it was longer than my brother's W116 300SD, so somewhere around 16 feet. I believe it is 0 gauge.
