Try to Order one online through E bay. I am currently in the process of redoing the wiring Harness on my Duster and found a nice one on E- Bay for under $100.00 Which is an excellent price when you consider Year One wants $300-$400 for a Engine Wiring Harness. As for taking the old one apart and rewiring yourself . Too much Betty Spaghetti work involved unless you want to take the time (especially if you have a hidden splice in a wire) Try to find one online if possible and just unplug the old and plug in the new. If you get one and need some help in installing it, Let me know.
