Wire Harnesses Are Our Business.

Our wire harnesses are manufactured right here in America at The Brillman Company and are truly braided with our premium cotton braid over PVC wire or our premium PVC wire (depending on the application). All wire harnesses are made with the correct gauge, color, wire and fuse holders (if needed). All terminals are soldered according to the original factory equipment. Wire harnesses do not include battery cables & spark plug wires sets, which can be purchased separately.
