take many notes/pics when undoing the old harness. If making it up a new one set the old one on your kitchen floor spread out and unwrap the electrical tape carefully maintaining the harness' shape/position. Make a new identical harness next to it & as you add 1 wire to start the new one make a wire on the old harness dissappear till the old one shrinks to nothing and the new one takes shape that way you have a carbon copy. Use identical color coded wires 1 gauge size (ie 14 instead of 16) larger than original. NAPA has brass male/female 1/4" terminals 725147/725145. invest in a quality wire stripper/crimper, one that grabs the wire then pulls the insulation sideways you'll not regret the price
