I'm looking at cleaning up my engine bay a bit by ordering one of those Rywire harnesses... I'm not the most handy when it comes to this stuff but I'm just wondering how involved of a process is it? Whats all involved? Is it pretty much plug and play for the most part? Take out the old harness and plug in the new? Are there any write ups on this? I've done some searching and came up with people asking about specific problems, or doing completely custom jobs... Any info would be appreciated. Thanks!
