i used 2 marine 5x wire harneses to run front to back in my boat (ended up using larger blocks than whats in the pic). then in the rear next to the battery i used a fuse/relay distribution block. this way i can keep all the high amp items at the rear and dont have to run big power up thru the front/gauge cluster. everything is fused and relayed.
Where can you buy these harnesses?
Is that white coated harness 4-wire?I used 9-wire heavy truck-trailer wire, got it from Napa, about a buck a foot, and some stand alone fuse panels from summit.DanielMash on it
