I recently picked up a 98 5.7 vortec, ecm, and wiring harness and plan to install in my CJ5. I've been doing a little research and I know given enough time I can hack up the factory wiring harness to work. 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?

Thanks
Doug
