My question for those of you that have done this before, if you had it to do all over again would you have spent the money and purchased a Painless wiring harness?

What 'Factory Wiring' do you think you have to 'Hack Up'?

All you really need from the factory harness is the 'Ignition' power feed,
the rest for the fuel injection sensors, injectors themselves, ect will NOT be in the factory harness since there is no fuel injection...

And there are SEVERAL COMPANIES that makes Fuel Injection harnesses to run between sensors, components and computer...
The one I like the most is from Arizona Speed & Marine, but there are SEVERAL...

Now, if you mean the factory Jeep wiring is crap and needs replaced,
I'd agree with you on that point,

For factory replacment harnesses, I sure wouldn't use Painless when there are so many others out there so much cheaper and just as good or better...
