So, Im new to the forum. I have searched around a little bit for some info and have came up dry so far. I have a chance to pick up a 94 mustang for relatively cheap but I havnt had a lot of experience with mustangs. I dont have all of the info yet, but here is what I do have...

The owner was a master mechanic for 30 years. The motor went out of it and he put a low mileage 3.8L from a convertible into it. He had to slightly modify the mounts, but the wiring harness plugged up fine. It will turn over, but he is not getting any spark. He was told the only motors compatible are the 94-95. So im guessing due to the lack of spark, there is some difference in the electrical system, but im not sure. Any ideas (Im guessing he looked over all of the basics, but you never know) ?

Thanks for the help
