Hello, No, I have an 89 YJ and I have purchased a LY2 4.8 from an 07 Silverado. The 4.8 has 38k on it and is in damn near new shape. I brought it home Yesterday and have almost every thing I need. I am missing the wire harness for the gas petal and maybe a couple of other parts. The motor had an auto trans on it and I am going to use and Advanced Adapters kit to get it all mounted up to my ax15 including a fly wheel. I want to use the factory Chevy fuel delivery and ignition. The older YJ has a mechanical speedo, but tach connections are a question. Also not sure if Oil pres and water temp are going to be issues(Different voltages???).
My wrangler has no emission controls and in my state does not need them as it is over 20 years old and it is registered outside of a Inspection and Maintenance district(I live in Oregon). The old 4.2 had a holley 4bbl and and MSD ignition
I need as much info as I can as to what I can strip from harnesses to take it to bare minimum wiz bangs and yet still be a runner. The real issues are the knowledge of the newer technology of the electronics.
My 72 year old father who lives with me was a mechanic all his life and owned his own shop untill 2004 when he retired. I have 2 associates degrees in electronics(transfer in engineering and transfer computer electronics) and, am a total gearhead. I do all my own welding and all my own repair and builds. from motors to diffs, This being said, there is plenty of mechanical ability just not enough knowledge of the new systems to know what has to stay and what does not. We understand knock sensors, O2s. MAF, MAP, and TPS. and temp sensors. Where we are a bit concerned the lack of a transmission for the transmission controls in the ECU. The harnesses that came with the motor has way more plugs then things to plug into so I know some of that can be stripped out.
Little things like where to pick up a good book and what book to get for guidance on the wire color codes and the like would be huge, as well as someone to bounce questions off of. Also if you know of any gotcha's and pit falls. I am also wondering about fly by cable rather then buy wire for the throttle. I am going to be writing up the entire swap and posting it with pics
I think that about explains what I am attempting to do so if you can offer any help that would be huge. Let me know if you are willing to give advice and pointers.
Thanks for your time and your interest
Here are a couple of pics of the motor
