Anderson power poles Get 'em from WestMountain Radio and a roll of 10 ga wire Be sure to fuse the leads at the battery Power poles come in many assorted flavors You can get 'em with leads attached (easiest) I have the tool to attach them. You can get 'em in a round snap in assembly I'd support the tractor to trailer line after the power connection (They are easy to pull apart) they are also "Asexual" that is there is no male and female
alternative is the good old reliable flat 2 connetor (Like the flat 4 trailer connector used on small trailers without brakes but onlky 2 pins)
I like the power poles though Use a lot of 'em.
You can also get heavier ones at NAPA Same general design but way heavier. These are often used on tow trucks for the jumper cables.
