Need Help!!!! Reply #15 – November 29, 2010, 12:58:41 PM the length matters as well, i would suggest RHH/RHW 90deg C wire oil resistant. Although not as important as the shunt wiring going to an amp gauge, it still cant be too long. I think the fuse links are about 5 or 6 inches on our cars.Ive made a few fuse links for people here, not too bad of a job. Quote Selected
