what size wire from battery to electrical connector for 12 volt items???

[goodguys75]

I have in the back of my truck a set of quick release 12 volt connectors, so I can run like say chain saw sharpener and other 12 volt items that i can have power in the truck bed... . what size cable should i run from my truck battery to the back of the tailgate area???? so just one positive cable and one negative cable to the back... . thanks andre

Need to know how many amps your tools require to make any recomendations

You have a constant 12V and ground in the trailer connector designed for charging a brake battery or running some lights in a trailer. Don't know if it's heavy enough, but you could make an adapter that will plug in the trailer connection to whatever connection you need for your tools.

I have a quick connector on the front and back of my truck to run either a 9,000 lb winch or a set of jumper cables. . I used a 0 gauge welding cable from one battery to both connections... and of course a ground wire from the battery to the frame and a ground at each end of the truck...

Hope this gives you an idea...

I had the same set up on my service truck. It was very handy

As others have said, Voltage isnt as important as amp load, both continuous and peak. Make sure you install the properly rated breaker or fuse as close to the source as possible, be careful to protect the power cables as you route them from the front to rear of the truck. If you arent requiring extremely high amps for a winch, or jumper cable leads. . etc. . I would suggest you use a 2 wire stranded core jacketed cable from an electrical supply house, it will give you an extra layer of abrasion protection as well as having a dedicated ground wire from front to rear. Just my . 02... .

I agree. Especially the dedicated ground. You don't want stray currents around our computers and modules.
