i think everything is a DIY project if you have a good mind set. i feel your pain i got an old f250 running after 12 years of sitting. same problem you have. me personally i think you could do it just fine. but if your not comfortable doing it, it might be a good idea to get it done by a professional mechanic. i wish the best for you.

I'd suggest getting a factory shop manual. It will show you the proper way to route the wiring harness. When you remove the old harness be sure you label each plug and connector. Then label the new harness accordingly. It's not as hard as it may seem, looking at the mound of wires, you just have to be patient and take your time. Some of the clips and fasteners may be hard to get to but I think with the shop manual as a guide you can do it. Give yourself a day or two for the project where you won't be interrupted. HTH. -Jim
