Will A Junkyard Obd1 Fit Into A Obd2 Deville Engine Harness If You Buy A Used Engine. 1994-1995 Concours Installed In A 1996 Sedan Deville. Whats The Specs.also Where To Get Pcm $$$$$

Two different systems. Sounds like a lot of trouble if it is feasable.
I think you will save yourself a great deal of heartache and probably money if you stick to 1996 componants.

so has any one ever used a 93/95 engine in a 96 if so what to change?:mad:
