Depend on how much you love your car is to you wanting to do it. A lot of work will be involved in converting the car over to OBD2.

You will need the entire engine and body harness, the computers from the OBD2 donor car. There is a sensor on the 95 engine (OBD1) that is in a whole different location in the 96 engine, so you would have to modify the harness to make it work.

Is it worth going through all that hassle to rip out all the wiring harnesses on both cars and shoving the OBD2 harness into your car, well that all depends on how much you know on how to do it, and how much love you have for your car..

Also, i'm pretty sure OBDI had higher outputs than OBDII

you know come to think about it....and i thought real HARD about it....for as much love as i got for this car and restoring it to its full potential i think i might just do it....now i just have to find the time to swap out the harness and pcm/ecu...i dunno if its me or the whole mod bug thing but man i just can't stop working on this car even if there really isn't much i can do to it lol

if anyone has an extra engine wiring harness for a 96/OBD2 3.3L laying around just sitting and they wanna get rid of it i'll be willing to ship it

I'd just buy an OBD-II car complete and be done with it. But that's just me!

I meant to buy an OBD-II car that you could drive rather than doing this pointless mod!

Does someone want to tell me I'm wrong when I say that I think the OBDII has less performance than it's OBDI counterpart? I think there was a page with all the specs for all years on allpar.com

If you're not going to actually do something with the readings...aka fix problems...what's the point?

I love how kids want to plug in their iPuds and say they did for readings and then Piss & Moan about actually having to fix a problem. For the $200+ they spent on the iPud adapter could've actually fixed real problems without it with people's advice on here. Just sayin'!!

I do not think there is a power difference, but perhaps the OBD I system was alot more forgiving for changes vs the OBD II. Mostly due to the fact OBD I is kinda dumb comparatively.


But, in honest having OBD II is only worth while for the do it yourself who wants to read codes. Otherwise it's no big deal and not worth changing the entire harness out.

really,, what im saying is , many have tried to change the EMC in our cars, but just as many have failed, the best thing to do is spend a few bucks and get a hand held scanner for OBD1 systems with a chrysler 1 adaptor, the connector is under the glove box,, plug in and read on,

Under Driver side Dash, between Steering column and center console. Blue connector. And not the most easiest to find adapter as well.
