I did this swap into a 95 v6.
We had to replace EVERY SINGLE HARNESS except the taillight harness. Also, we ordered an SCT tuner being told it could delete PATS. It doesn't. We ended up taking it to a local shop that added in PATS to the car as well as tweaked some of the electrical for us.
I can tell you a bit more details if you like
It was a HUGE project my husband and I did in our garage...you will thank yourself for having a donor car, trust me.
