Sorry man... but punctuation helps... That hurt to read.
Also, from what I've read, it'* really hard going from a N/A engine to a supercharged engine, especially if you started with the 1995 SSE that has the OBDI/II computer vs the strictly OBDII. (I know, I have a '95 SSE).

ok, let me digest this post.......

you have a 95 SSE
you had a blown motor
you had a new one in again that was crap
you now have a Series 2 L67 supercharged

Now my questions......
are you running the orignal Trans that came with the NA motor
do you have the Orignal motors wireharness??

answer these questions as there might be a easy option for you....

ok good......now we can get down to business.....

Since your car never came with the Series 2 L67 you just cant get a harness.....

here is what im thinking.....

you use the orignal L36 NA hanress running the L67 motor....the car will run and the trans will function properly

there have been a few members that have swapped the topend of the L67 onto the L36 motor with out problems....the only problems are Killing the trans really quick because it cant handle the power so this is basically what you did because the blocks are the same and all the other goodies

now this would be by far the least reliable setup because of the trans

Whoa....glad that we had a translator for that...thanks Pat!

Todd, welcome to the club. If you are planning on continuing serious work on this car, a factory service manual is a must. It will have the information you need. If not that, at least a subscription to AllDataDIY will also be helpful to you.

Dogman, as you can see at this point, your new engine isn't compatible with your old engine wiring harness or PCM.

I suggest getting a PCM AND Wiring harness from a 96-99 SSEi. It'* going to be a neat trick though, considering the PCM location is different in 95 when compared to the other years. And the wiring harness will differe because of it.

A little research and the right manuals may have saved you alot of headaches.

In your future posts, please try to use puncuation and spell correctly. Your posts so far are VERY difficult to make sense of.

That still leaves you in an interesting position:

Your PCM is under the glovebox. Which means your wiriing harness starts and ends there.

The 96 PCM was located behind the left front headlight. See the problem now? It'* a big task. VERY big. And it'* going to be a mess. I think the best thing for you at this point is to buy a 95 FSM and a 96 FSM and a good meter.
