240Z2NV Posted January 2, 2008 Share Posted January 2, 2008 Just passing along something I learned from a guy at the JY today. The BMW 7, 5, and 3 series cars with 6cyl. [or bigger] engines have the battery mounted in the trunk from the factory. They have a VERY HEAVY gauge cable from the trunk battery to the starter in the engine compartment that took all of five minutes to remove. Also, the ground cable goes from the trunk to just under the passenger REAR seat. VERY NICE cabling that cost $7 for the pair, and is damn-near tailor made for mounting your batteries in the rear compartment. Quote Link to comment Share on other sites More sharing options...
Evan Purple240zt Posted January 2, 2008 Share Posted January 2, 2008 Cool tip. Same deal with many of the higher end benzes. Evan Quote Link to comment Share on other sites More sharing options...
smoorenc Posted January 2, 2008 Share Posted January 2, 2008 Where can we get this cabling at for $7.00 ? Quote Link to comment Share on other sites More sharing options...
240hoke Posted January 2, 2008 Share Posted January 2, 2008 Smoore- I think he was just quoting his JY price. That is a really good idea, ive never thought about using the cable, how did the length work out? They also have a "isolator" in the engine compartment that would be nice for jumping the car etc. Another great source for wire which is super flexible and not terribly over priced is welding ground wire, most welding shops will also crimp whatever terminal you need on it as well.

240Z2NV Posted January 3, 2008 Author Share Posted January 3, 2008 '240Hoke' you were correct. I was quoting what I paid at Pick-n-Pull during their Half Price promo. I don't know the EXACT result of the length because I am not on that phase of the never-ending project; however, I held it up to my 240Z, and it is more than long enough. Hadn't planned on mounting battery back there. Thought that I was going to use the small Odyssey battery in the OE place so that I could mount the PCM next to it on that shelf. It is far enough off, that I'm not going to sweat it for now. For seven bucks it was worth it just to have this added option. Quote Link to comment Share on other sites More sharing options...
