Before anyone gives me crap about "use the search" I have read through several posts and the only thing I ever seem to get is a list of needed parts, and a bunch of people conversing about code fixing. What I want to know is if it will be easier to gut my 2000 neon completely, including alll wiring, and replace it with the SRT-4 harness or trouble shoot the existing interior harness and just swap the under hood harness out? Do I need to swap the K-frame piece? And lastly is there anyone with a step by step how to? I am leaning more towords the complete harness swap as the car would think and act like an SRT-4. Additionally would it make more sense to save myself all of that work and just install a Mega-Squirt?

just install the megasquirt i did on my swap then i switched out for afc cause megasquirt was a bit confusing but the k frame isnt nesscary i didnt do it on my swap, there arent really a step by step cause theres SOOOO much things you have to do and swap out the interior and underhood... the interior isnt nesscary but then you wont throw codes but the underhood is nesscary unless you wanan redo you whole wiring harness you have now

What I am asking is if I would need to do ANY rewiring if I installed a MegaSquirt. If I installed every componet of the MegaSquirt I dont think I would need to rewire anything....would I? I was thinking I could leave the 2000 PCM in place and control the motor with the MegaSquirt

the easiest thing you can do is strip your car and swap everything over (and i do mean everything)

that will give you trouble code free operation without a doubt.

when i did seisephiroth's swap, we swapped everything and his car left here w/ no codes to speak of. only code he got on his way home was from the downstream O2 sensor (becuase he installed a downpipe w/ no cat)

Thanks! So you seem to think swapping EVERYTHING is the better route. What kind of a time frame am I looking at? From what I can see I disconnect the harness under the dash and the just start going down the line unhooking things for the interior. Then I pull the harness through the firewall groment and pull the underhood side correct? is there anything I need to be aware of? If I use EVERYTHING from the SRT-4 I should have complete functionality from all of my components (AC, ABS, ETC...) right?

correct.

swap all wiring, swap the hvac system, swap the nvld, leave nothing stock...

if you only leave the body as stock neon parts and everything else is from the srt4, what do you have to lose?

It all just seems so overwhelming...obviously it has been done before though, so I should be able to do it.

Swapping the whole harness/instrument cluster is the way to go, because not only are there issues such as the IAC being different from 2001-up cars, the SRT will also have the sentry stuff that needs to be installed, so as long as you have a complete donor car w/keys you shouldn't have any issues, and with everything stock to begin with you'll know that any problems you may encounter aren't something that wasn't wired or programmed correctly. If everthing works like expected then start playing!

VERY valid point...I will be starting a project log on this soon!
